I saw an experiment called volcanic eruption in a book called I Love Science on Saturday morning. Curiosity impelled me to do it.
According to the requirements of the experiment, I prepared a cup, a bottle of vinegar, a bottle of hand sanitizer, a pack of baking soda and a plate. I poured dozens of cups, then a little hand sanitizer, then I put the plate under the cups, and finally I poured some vinegar into the cups. I will hold my breath and see what happens. At first, the baking soda and hand sanitizer in the cup were still fine. After a few minutes, they turned into foam. It's just a little foam, and it will keep rising for a while. After only 10 seconds, they poured out of the cup like a swarm, overflowed the cup and flowed directly onto the plate. At this time, I was both excited and surprised. I stared at the floating foam for fear of missing any details. My heart is jumping like a rabbit. After a few minutes, the bubbles gradually disappeared. I witnessed the spectacular scene of volcanic eruption, but I couldn't get back to God for a long time.
What's the secret? I quickly opened the book "I love science", which didn't mention anything. I thought about it for a while, but there was still no answer. After searching online, I finally understand the mystery! It turns out that baking soda and vinegar produce a lot of bubbles. Hand sanitizer played a catalytic role! Because ammonium bicarbonate in baking soda powder reacts with hydrogen ions in white vinegar to generate carbon dioxide and form bubbles, these bubbles are mixed with liquid and rushed out of the bottle mouth, forming a scene of volcanic eruption.
Doing small scientific experiments made me understand the scientific truth while playing and also exercised my practical ability. What a cool experience it is to walk into them through thinking and witness them through hands-on experiments.
One day, I was reading a book about scientific production, and suddenly a title attracted me-Volcanic Eruption. Isn't volcanic eruption a natural phenomenon? Can this be done? My heart is full of doubts. So, I did the experiment with curiosity.
First, prepare some materials: baking soda, red pigment, water, detergent, white vinegar and several cups. Pour baking soda, red pigment and water into the first cup and mix well, then add detergent and white vinegar into the other cup. The experiment is about to begin. Pour the liquid in two cups into a glass bottle with a small mouth and a large body, and put a larger basin under it.
The miracle began. The liquid in the bottle turned into foam like magic. I can't believe my eyes. I quickly put my face together and stared at the bottle mouth. Afraid of missing the process of bubble change. The foam stirred in the glass bottle and suddenly gushed out of the bottle like a wild horse out of control and flowed into the basin. At this time, I was surprised and excited to see the bubble pouring out, but soon it gradually disappeared. No wonder the experiment is called "volcanic eruption", which is as spectacular as volcanic eruption! But I turned my head and thought, "What is the reason?"
I was puzzled to find the answer in the book. It turns out that baking soda and white vinegar will react chemically, just like shaking soda will produce foam, and detergent plays a catalytic role, so it constitutes such a magical "volcanic eruption" experiment.
This interesting experiment made me fall in love with science and let me know that there is science everywhere in my life. Only by continuous exploration can I understand the mystery of science.
Many cartoons have breathtaking and spectacular scenes of volcanic eruption, so I want to experience it myself.
I have prepared vinegar, baking soda, red dye, paper cups and some water. I'm going to start the experiment. Only these things can really produce the effect of volcanic eruption? I'm beginning to feel uneasy.
The experiment began. I first pour baking soda into a paper cup, then stir the red dye with some water, and then pour the red dye into a paper cup filled with baking soda. At this time, baking soda and red dye are mixed together and become a red liquid. How beautiful! We are about to enter the final step. Can the experiment succeed? I'm getting nervous. I gently picked up the white vinegar and slowly poured it into the paper cup. Miracle appeared, and the red liquid instantly flowed out of the generated paper cup. They are like a market, pouring out layer by layer. After a while, the foam began to shrink and the water surface gradually returned to calm. At this time, I found that there was little liquid left in the paper cup.
Later, I learned that the experimental principle of volcanic eruption is that baking soda is an alkaline salt. When encountering acid vinegar, a chemical reaction will occur, producing a large number of bubbles, thus forming a scene of volcanic eruption. I think the scientific experiment is really amazing!
This morning, it was sunny. Teacher Nan came into the classroom and said mysteriously, "Today we are going to do a volcano eruption experiment." Said, and took out the equipment from the drawer, including volcano molds, syringes, spoons, stirring rods, baking soda and citric acid. Citric acid tastes like hamster. It is shaped like a small triangle and its color is white. Baking soda is as big as sand and pink in color. Some students observe carefully, some record their findings, and some wait to observe. ...
Our experiment has begun. First take a spoonful of citric acid with a small spoon, then a spoonful of baking soda, and then stir it evenly with a stirring rod. Inside the volcano model, it looks like pink cold particles and finally swims into the water. In an instant, red lava spewed out from the volcano. When the foam of the molten paddle explodes, it will make a "popping" sound. In a blink of an eye, the melted oars have gathered into a river with blood color at the foot of the mountain.
After the experiment last night, Nanshi asked a scientific question: Why do baking soda and citric acid keep bubbling and spewing out when they meet water?
So it is: citric acid and baking soda neutralize to produce carbon dioxide. They erupt like coke and shake violently to produce bubbles. After listening to this principle, I suddenly feel that scientific experiments are also very interesting!
Such a small experiment made me understand a lot of knowledge and truth!

At first, I slowly poured a small amount of water into a small transparent cup; Then, I poured three times as much oil as water and poured it down the cup wall bit by bit. Hey, why didn't the oil sink? The team leader said: water is heavier than oil, so water is below and oil is above. They are incompatible with each other and have a clear dividing line. I suddenly realized. I found a dozen drops of flame-like pigment, which formed big bubbles in water and oil and contained pigment. The pigment sank like a red pearl, and then floated up gently to the boundary between water and oil. Then I slowly put the effervescent tablets into the cup. Suddenly, the effervescent tablets exploded and the volcano erupted. A column of water appeared in the cup, soaring into the sky. It seems that some snakes are trapped in the water and want to escape. The students next to me stared at me, surprised, and I couldn't believe everything in front of me. I clapped my hands in surprise and shouted, "Awesome! Our experiment was successful! " I thought again: why does a small effervescent tablet burst out with such great strength, and why? Later, the volcano stopped erupting, and I smelled it hard, which smelled like coke. The water and oil in the glass turned orange, just like a glass of orange juice. I wonder if I can drink it? What will happen if you drink it? The flame faded away. I feel tired of playing. The scent of the dragon is getting stronger and stronger, and there are a lot of blisters on its surface, which slowly rises to the surface of the water, as if an elf had ascended to heaven. ...
Haha, isn't volcanic eruption amazing? Have you seen it? But why do undersea volcanoes erupt? I think you must want to know the secret. It turns out that effervescent tablets will produce a lot of carbon dioxide gas when put into water, and the carbon dioxide gas will quickly push the water containing pigment above the oil layer. Because oil and water are incompatible, colored water will soon fall from the oil layer, thus forming a submarine volcano. ...

First, I took out a transparent cup and poured some water into it. Then I poured about three times as much oil into the water along the cup wall. Xiao Ming said, "I found the dividing line between water and oil." I tried to stir it with chopsticks, and sure enough, the water got into the oil, but it recovered immediately. Hey, what happened? Xiao Ming said, "Water is heavier than oil, and the two are incompatible." I suddenly realized. I added a dozen drops of red pigment, and the pigment turned into little pearls, jumping up and down like a little girl in a red skirt dancing.
It's time to witness the miracle. I put the circular effervescent tablets in. Hey, why didn't it boil? Did I do something wrong? When the boiling plate sinks, the water finally boils, and soon many small bubbles are produced. Small bubbles break through the line and rotate in the oil, forming a vortex and forming a yellow water column. The pigment exploded like a time bomb, and the yellow water column instantly turned into red magma, rolling and surging. I said, "The volcano is going to erupt!" The students cheered loudly, some stared at the glass, some opened their mouths, and some shouted, "We succeeded, we succeeded!" " "Why is the little effervescent tablet so powerful? I smell it. It smells good! The blisters rose slowly, like immortals.
Isn't it amazing that volcanoes erupt? You saw it, but do you know why? It turns out that when effervescent tablets are put into water, a large amount of carbon dioxide gas will be generated, which will quickly push the pigment water to the oil layer. Because oil and water are immiscible, colored water will quickly fall back from the oil layer, thus forming an "undersea volcano" ...

Today, we did a little experiment. First, I slowly pour a small amount of water into a small transparent cup. Then I slowly poured three times as much cooking oil as water into the cup along the wall. Hey, how did the water sink to the bottom? Xiao Ming told me that water was heavier than oil before it sank. I suddenly realized. After that, I took out the flame-like pigment and dropped a dozen drops into the cup. After the pigment enters the water, it looks like a little red pearl, like a lively little girl, eager to do something. Why is this? It turns out that the pigment is wrapped in oil after dropping into water, so it has a shape. Finally, I slowly put a round effervescent tablet into the water. I think the experiment will succeed?
Just put it down. It's time to witness the miracle. Those pigments soon changed from small bubbles to big bubbles, and they seemed to grow up and chase each other ... A water column appeared in the cup at once, sprayed up and down for a while. I clapped my hands and shouted, "The volcano erupted, erupted, it was amazing!" " "Look at them sink in the bottom of the cup. I think they are tired of playing. After a long time, the big bubble burst into a small bubble, which gave off a burst of orange juice. I sniffed hard. It smells good. I really want a drink. I thought to myself, how can a small effervescent tablet be so explosive? Why on earth is this? I was both cheering and surprised. My eyes are round and my mouth is wide open. The students said in unison, "Our experiment succeeded! "Oh, all this is amazing! What surprised me even more was that water and oil were not mixed together, and many blisters appeared on the water surface. They flew slowly to the surface of the water, as if the elves were ascending to heaven.
Haha, volcanic eruption is amazing! You've seen it! But why did the volcano erupt? You must want to know more about this secret. It turns out that when effervescent tablets are released into water, a large amount of carbon dioxide gas will be produced, and the carbon dioxide gas will quickly push the water containing pigments to the oil layer.

I first took out a transparent cup and poured a small amount of water into it. Then pour three times as much oil as water into the cup along the wall. At this time, there is a clear dividing line between water and oil. Hey, why didn't water and oil mix together? Xiao Ming said that because water is heavier than oil and immiscible, there is a clear dividing line. I suddenly realized. After that, I took out the pigment with the same color as the volcano and threw it into the water, like hitting a dozen bullets in the water, from top to bottom, in turn; They are jumping around like cute little girls again. Are they going to a big dance? Finally, I slowly put a round effervescent tablet into the cup.
With a bang, it was put down, and it was time to witness the miracle. Pigment instantly changes from small bubbles to big bubbles, and jumps up as quickly as it grows up. They pushed each other and chased each other ... a string of magma rose rapidly like a tornado. I clapped my hands in surprise and shouted, "Wow, look, it's a tornado!" " "It kept turning and turning. After a while, the big bubbles broke down into small bubbles, and the magma slowly sank into the water. Seeing them lying at the bottom of the cup, I think they are tired of playing. I sniffed hard and gave off the smell of coke. I couldn't help swallowing. I really want a drink! I think a small effervescent tablet is so powerful. What is the reason?
The students' eyes are about to explode, staring at the cup and cheering: "Oh, yeah, we did it!" " "I can't believe what I saw. The team leader also sniffed it with his nose and said, Wow, it smells good! We clapped our hands together excitedly: "Great, our experiment succeeded!" " "How so like? Can I have a drink? There are many bubbles floating on the water, and they fly to the water slowly, like elves ascending to heaven.

First, I pour a small amount of water into a small transparent cup. Then I slowly poured three times as much oil as water into the cup along the wall. Hey, why is the oil impetuous instead of heavy? Oh, the team leader said that because water is heavier than oil, and oil and water can't be mixed. I suddenly realized. After that, I picked up a bottle of crimson pigment, unscrewed the lid and dropped a dozen drops. Those little pigments hit the water like bullets; Like a little girl again, alive and kicking, like attending a dance. Finally, I put a round effervescent tablet in the cup.
Now, it's time to witness the miracle! Suddenly, a short transparent column appeared in the cup, which jumped up quickly. Small bubbles became big bubbles in the blink of an eye, as if they had grown up, and they were crowded and touched. Like a lively little girl, attending a grand dance. There seems to be a tornado in the cup, and small white bubbles appear. I shouted in surprise: "Dragon turns to wind, tornado turns!" " "A small effervescent tablet, why so much? Why on earth is this? " Bang-",suddenly there was a fragrance in the cup, and my mouth was watering. I really want a drink! But why is it fragrant? Bubbles float on the water and slowly fly to the sky, as if an elf had ascended to heaven!
The experiment was successful. The students clapped their hands and shouted, "Great, it worked!" " "I can't believe it. The team leader put his hand on the top of the cup to feel it. Other students also smelled it: "It smells good! "
Haha, the eruption of Mars is amazing, but why did the volcano erupt? You must want to know more.

Experimental Composition of Volcanic Eruption 10 Have you ever heard of volcanic eruption? Have you ever seen a volcanic eruption? Please follow my little experiment to enjoy it.
First, pour a small amount of water into a transparent cup. Then, add three times more oil than the water in the cup and pour it slowly along the mouth of the cup. Hey, why did the water sink and the oil didn't sink? The team leader said that because water is heavier than oil, it is immiscible. I suddenly realized. Then, I took out the flame-like paint and dropped a dozen drops. Finally, I slowly put a round effervescent tablet into the cup.
A miracle happened! Suddenly, the pigment inside burst, and the red pigment turned yellow, like popcorn in a cup, and like a lively little boy jumping around in it, so happy. Like a small fish trying to escape. The volcano "erupted", and small bubbles quickly rushed up and instantly became big bubbles. They pushed each other and chased each other ... I clapped my hands in surprise and shouted, "The volcano erupted, erupted!" " This is amazing. After a while, the big bubble became a small bubble again. Why does a small effervescent tablet explode so powerfully? Why on earth is this? We sniffed hard, ah, it smells good! It smells sour and sweet. I really want a drink! There are many bubbles floating on the surface of the water. They fly slowly to the surface of the water and fly to the sky like elves. The students also shouted: "Our experiment succeeded, yeah!" The team leader raised his hand to probe the mouth of the cup, smelled it again and said, "It smells good!" "Is this water drinkable? What will happen if you drink it? Look at the bubbles sinking at the bottom of the cup. I think they are tired of playing.

Carbon dioxide gas quickly pushes water containing pigment onto the oil layer, because oil and water are immiscible, colored water quickly falls back from the oil layer, thus forming a "submarine volcano" ...
Experimental composition of Volcanic Eruption 1 1 I heard that the experiment of Volcanic Eruption was magical, so I did this magical little experiment. The materials to be prepared in this experiment are baking soda, stirring rod, white vinegar, detergent, plasticine, plastic bottle, tray and pigment (preferably red).
First, I carefully put the tray on the ground and put the plastic bottle in the center of the tray. Then, I carefully knead the plasticine into the shape of a volcano, especially the slope of the volcano, so that it can be pinched tightly. A model of a volcano has been initially completed.
Dig a hole at the top of the volcano. How wide and deep should this hole be dug? It depends on the size of the bottle! The width of this hole is a little wider than the bottom of the bottle and the depth is a little higher than the bottle. After the hole is dug, carefully put the bottle into the "volcano" hole and fill the gap between the bottle and the hole with plasticine. In this way, a "volcano" is completed.
Then, I poured the white vinegar into the bottle, and a pungent smell came to my face. I covered my nose tightly and managed to finish the white vinegar. Then add 5- 10 drops of pigment to make it bright red. Next, add a little detergent. Finally, stir with a stirring rod. In this way, the pungent "magma" is completed.
Here comes the most crucial step-pouring baking soda into the bottle. At this time, my heart has started to "beat": this is the most critical step. If I'm wrong, wouldn't it fall short and give up all my previous efforts?
I must succeed, I secretly hope.
In a short time, many "hot" pungent "magma" flowed out.
"success!" I shouted in surprise.
Huh? Why are there bubbles in these "magma"? I feel very confused.
It turns out that baking soda is sodium bicarbonate and white vinegar contains acetic acid. Sodium bicarbonate reacts with acetic acid to produce sodium acetate and carbonic acid. Carbonic acid is unstable and will continue to decompose into carbon dioxide and water.
This "volcanic eruption" experiment is really amazing.
One day, I saw a small experiment in a science book, and a volcano erupted, so I started to do it.
First, according to the introduction in the book, prepare water, transparent cups, some plasticine, a bag of baking soda, a spoon, lemon-flavored detergent, a chopstick, a paper plate and red ink. Then use plasticine to make a small "volcano" on the paper plate, hollow it out in the middle as a crater, pour a spoonful of baking soda into the mouth of the "volcano" and drop 3 to 5 drops of lemon-flavored detergent. Then, add 50 ml of clear water to the transparent cup, drop a few drops of red ink, and stir evenly with chopsticks to make it turn red. Everything is ready, and finally, it's time to witness the miracle! I slowly poured this glass of water into the crater, only to hear the sound of "zi", and instantly "red molten slurry" emerged from the crater.
"Volcanic eruption" experiment succeeded! I jumped for joy!
Later, I checked the information on the Internet and found that the lemon-flavored detergent used in the experiment contains citric acid, which is acidic and baking soda is alkaline. When they are mixed, they react chemically to produce carbon dioxide gas. Carbon dioxide and detergent produce a lot of foam when they meet red liquid, forming a "volcanic eruption" scene.
This experiment made me learn knowledge and enriched my after-school life. I will do more experiments and gain more knowledge in the future.
On Saturday morning, my mother bought me a box of experimental equipment. I couldn't wait to open the box, take out the instructions, read them carefully, and decided to do the scientific experiment of "volcanic eruption"
First of all, I prepared all the raw materials for the experiment, including sodium citrate, soda and melanin. The experiment officially began. I take out an empty drink bottle, put a little water in it, and then add three drops of melanin. I chose the color of the melted pulp-orange red. Later, I added soda water to the drink bottle filled with bright red water. Finally, I added sodium citrate in fear. Quietly waiting for a little while, hey, why didn't you respond? I was thinking, is there too little water? Therefore, I added some drinking water. At this moment, something wonderful happened. The lava in the "active volcano" spewed out, and the red foam lava produced a small mushroom cloud, which kept pouring out from the cork. It's spectacular. At that time, I really wanted my mobile phone watch to take this photo. Unfortunately, just open the mobile phone watch, "the volcanic eruption is over.
In this research, I still have one problem unsolved. Why do soda and sodium citrate come out together? I asked my mother, and she told me to look for the answer in the book myself. I can only read science books patiently and finally find the answer. It turns out that soda and sodium citrate will have an acid-base reaction together, which is also a common chemical change in daily life. It will be very labor-saving and neat for mom to scrub the sink with this basic principle. A small experiment improved my professional knowledge.
"Volcanic eruption" experimental composition 14 It is said that putting a few mints in carbonated drinks can simulate the scene of volcanic eruption and spray very high. To prove this, I did an experiment.
First, I prepared a bottle of Sprite and two mints. Next, I put mints in Sprite. Sprite began to make a sound, releasing a large number of small white bubbles, but after the bubbles were two centimeters above the liquid level, they stopped growing and did not erupt at all. Seeing that the sound of ""is getting smaller and smaller, the experiment of "volcanic eruption" will fail. The mother standing by had a brainwave, brought baking soda and carefully poured it into Sprite. At this time, a miracle happened, and more and more white bubbles poured out of the bottle mouth, much like the scene of volcanic magma flowing out of the crater on TV. Finally, the small bubbles slowly disappear, leaving clear water.
The principle of "volcanic eruption" is that after adding baking soda and mints to Sprite, a chemical reaction occurs and carbon dioxide is released into the air.
This little experiment made me learn more scientific knowledge!
