Question 1: Who invented soap? Soap is a very common household product. Its invention was not created by one person, like the way of inventing zippers and ballpoint pens. In fact, soap is one of the most important chemical inventions. It tells people that chemistry can produce wonderful effects-make dirty hands clean; Make two completely different things into a completely new thing. The invention of soap inspired mankind to explore. There may be an invisible "magic" in the world, which can show us how to open mysterious treasures and create many new things. However, how did the earliest soap come into being? A long time ago, something happened in the palace of ancient Egypt: one day, the king held a grand banquet to entertain his guests. In the middle of the night, people went to dinner, and the chef in the kitchen was busy tidying up the dishes. Someone accidentally knocked over a pot of cooking oil next to the stove, and the oil flowed into the stove and mixed with charred charcoal. A Gaul (ancient French) chef, worried about causing a fire, hurriedly took oily charcoal outside. Strange to say, when he washed his hands, he found that his greasy hands were smooth and much cleaner than before. He told his companion about it, which aroused everyone's curiosity. So everyone tried it again and agreed: great. Later, they put some charred charcoal in the stove, poured some oil on it, and washed their hands with it after work. When the king knew about it, he told others to do the same, and made a round stick to facilitate the people in the palace to wash their hands. This is the earliest soap. In the 2nd century A.D., the technology of making soap handed down by Gauls has made great progress. People use beech trees to burn wood ash and then mix it with sheep fat to make a paste. Soap is not only used for washing hands, but also for washing other things: clothes, tableware and hair. With the wide application of soap, soap production has mushroomed. Many soap workshops have been established in Marseille, France and savona, Italy, because these places produce olive oil and alkali with many raw materials. The soap they produce is also sold to other countries. Russia only imported soap during the reign of Peter the Great. In the tsarist era, only people in the palace and nobles had the right to use it. Serfs were forbidden to use soap and could only use alkaline water (clear water after firewood ashes were boiled in water). If you violate it, you will be punished. Until 179 1, French chemist Lubran invented the method of making alkali, and the secret of washing hands with charcoal mixed with oil was uncovered. When oil and alkali are mixed together, the compound produced is soap storage, he said. Charcoal contains some alkali, which will react with oil pollution and dissolve in water. In this way, soap can be produced in large quantities. Although soap was invented a long time ago, it was really widely used after19th century. Whether washing your body or washing clothes with soap, its advantages are self-evident. Washing clothes in rivers, lakes and seas with soap is much better than washing powder, and soap is not easy to make rivers, lakes and seas go bad. Because it is easy to be digested and absorbed by microorganisms in water, it is also easy to form precipitation in sewage and sink to the bottom of the water. Washing powder is no good. If silk and wool are washed, soap is better than synthetic detergent and does little harm to fabrics. Nowadays, there are many kinds of daily detergents, especially the advertising war of washing powder makes the status of washing powder increase day by day. Although soap is very old, it is still out of date. And the uniqueness of soap. In daily life, people still have a deep understanding that it will not be replaced by other washing products, but will have greater development and wider application. For example, the mixed soap developed by adding spices and medicinal materials to soap is a good example.

Question 2: Who invented the cored soap? Soap Soap is a very common household item. Its invention was not created by one person, like the way of inventing zippers and ballpoint pens.

The invention of soap inspired mankind to explore. There may be an invisible "magic" in the world, which can show us how to open mysterious treasures and create many new things. However, how did the earliest soap come into being? In 70 A.D., the Roman scholar Pliny first made a block soap from sheep oil and plant ash. One day more than 5000 years ago, in the palace of ancient Egypt, King Khufu was entertaining guests. It's a mistake that the kitchen is as busy as a bee at this time. A careless little chef accidentally dropped the oil box into the charcoal ash. He was scared and worried about being reprimanded, so he took advantage of people's inattention to hold the charcoal ash mixed with oil into the mud pit in the corner outside the kitchen. When he went back to wash his hands, he accidentally found that his hands were particularly smooth and clean, so he invited several other partners to try them. Sure enough, everyone's hands are smooth and clean. Knowing this, the king ordered his men to make charcoal ashes stained with oil according to the chef's method to wash their hands. This is the earliest soap. In the 2nd century A.D., the technology of making soap handed down by Gauls has made great progress. People use beech trees to burn wood ash and then mix it with sheep fat to make a paste. Soap is not only used for washing hands, but also for washing other things: clothes, tableware and hair.

Serfs were forbidden to use soap and could only use alkaline water (clear water after firewood ashes were boiled in water). If you violate it, you will be punished. Later, the Roman scholar Pliny made block soap from sheep oil and plant ash for the first time. Later, this soap-making method spread to Greece, Britain and other places. Russian emperor Peter I also learned this technology, but only people in the palace and nobles used it. Queen Elizabeth I ordered a soap factory to be built in Bristol, where boiled sheep fat was mixed with caustic soda and chalk to make soap. Although the quality of soap has been greatly improved than before, the price is very expensive and most people can't afford it. It was not until 179 1 that the French chemist Lubran obtained the method of electrolytic salt. After making caustic soda, the secret of washing hands with charcoal was uncovered, which greatly reduced the cost of soap. At this time, high-quality soap gradually entered the families of ordinary people. Although soap was invented a long time ago, it was really widely used after19th century. Whether washing your body or washing clothes with soap, its advantages are self-evident. Washing clothes in rivers, lakes and seas with soap is much better than washing powder, and soap is not easy to make rivers, lakes and seas go bad. Because it is easy to be digested and absorbed by microorganisms in water, it is also easy to form precipitation in sewage and sink to the bottom of the water. Washing powder is no good.

Question 4: Which country did soap originate from? Because the ancients used Gleditsia sinensis to wash clothes in the Yellow River valley, and there were no Gleditsia sinensis trees in the Yangtze River valley, they found another tree. Its fruit was the same as Gleditsia sinensis, but it was more plump than Gleditsia sinensis, so it was named Gleditsia sinensis.

According to historical records, the earliest soap formula originated in Mesopotamia, West Asia, and began to appear around 3000 BC.

Question 5: The origin of the word "soap" After reading the answers from so many friends upstairs, I don't want to answer any more. It was not well covered up and not adopted by the following, which affected my adoption rate in vain. But after reading it for a long time, I really didn't see a friend who knows botany answer, so I'd better join in the fun:

First of all, in ancient China, soap and pancreas were not the same thing! Soap always refers to a plant, and the pancreas is indeed a semi-synthetic washing product. Only in modern times, after the vegetable soap gradually faded out, the pancreas gradually replaced the vegetable soap and gradually confused with the names of vegetable soap and chemical soap.

Let's start with Gleditsia sinensis and soap:

Gleditsia sinensis-also known as Gleditsia sinensis, Gleditsia sinensis, Gleditsia sinensis, Gleditsia sinensis, Lespedeza spinosa, Gleditsia sinensis and Gleditsia sinensis-belongs to Leguminosae/Pistaceae/Gleditsia sinensis.

Soap-also called Gleditsia sinensis. Gleditsia sinensis Gleditsia sinensis Gleditsia sinensis

The biggest difference is that Gleditsia sinensis has thorns and Gleditsia sinensis has no thorns. However, both fruits, namely Gleditsia sinensis, contain saponin, which is a natural plant surfactant with foaming, decontamination, emulsification and other functions. Compared with real chemical soap, Gleditsia sinensis is resistant to hard water and does not contain alkalinity.

By the way, what is the pancreas? There was a kind of bath bean in Tang Dynasty, which was made by grinding pig pancreas into paste, mixing it with bean powder and spices, and drying it. In the Ming and Qing Dynasties, the folk improved bath beans, which were made by mixing and grinding pig pancreas, sugar, natural sodium carbonate, lard and spices in proportion, heating to 40℃ and pressing to form, and called "pancreas".

Lard in seed pancreas is partially decomposed into fatty acids by lipase, and then saponified by sodium carbonate into real fatty acid soap (the main component of modern chemical soap). However, this decomposition and saponification are incomplete, so although the product looks like modern soap, its composition is a semi-saponified mixture containing enzymes, which is different from modern soap and soap. But it is very similar to the handmade soap that has been sold well online in the last two years! Handmade soap is actually semi-saponified soap.

As for the later generations, among the three names of pancreas, soap and Gleditsia sinensis, you have me and I have you, which is what needs to be carefully distinguished.

Question 6: Who invented the first bar of soap? What nationality? According to historical records, the earliest soap formula originated in Mesopotamia in West Asia (meaning "the place between the two rivers", meaning between the Euphrates River and the Tigris River). About 3000 BC, people mixed 1 part oil and 5 parts alkaline plant ash to make a detergent. There are many legends about the origin of soap in Europe. Speaking of Gauls in ancient Rome, sheep oil and beech ash solution were stirred into a thick shape every holiday, applied to hair and combed into various hairstyles. Once a festival was caught in heavy rain, and the hairstyle was ruined, but people unexpectedly found that the hair became clean. It is also said that when the Romans sacrificed to the gods, the fat of roasted cattle and sheep dripped into the plant ash, forming a "grease ball". When women wash clothes, they find that clothes stained with "oil balls" are easier to clean. This shows that people have used animal fat and plant ash soap for thousands of years.

Question 7: The invention of soap. Reference answer: 1. Decide the future of mankind and create the future of the motherland. (Copy the original sentence) Analysis: This kind of question is an examination of the content of the article. When doing this kind of problem, we must first locate it. In the fourth paragraph of the article, we find "the responsibility of young people", and the answer is often near this sentence. The content behind this sentence is to tell us what to do. From the front of this sentence, we can see that "the future of mankind depends on you, and the future of the motherland depends on you to create", thus getting the answer.

2. Enhance the readability of the article, improve the expression effect of the language, and make it more colorful and rich in content. Analysis: When doing this question, students can easily understand it as an examination of the role of argument, but if you look at the question carefully, you will know that this question examines the understanding of the role of "quotation". Quoting famous people's words can increase the literary grace of the article, make it more readable and richer in content.

3. It just fits the meaning of the question. Analysis: This question examines the parody that "young people are the sun at eight or nine o'clock in the morning". When doing this kind of questions, we must grasp the requirements of imitation, that is, the number of words is roughly the same; The use of figures of speech is consistent (using figurative figures of speech); Just grab the key words of the example.

(1) Young people should study harder. "You must have a deep understanding of the voluminous China classical literature." (2) Young people should cherish time. "Time is short for young people and old people, so we must cherish it." Analysis: In the eighth paragraph of the article, the elder's entrustment "Young man, take care" appeared, so we should draw a conclusion and analyze the whole article. The fifth paragraph of the article puts forward the reason, and the sixth paragraph explains the reason M, that is, "first, we should study, and second, we should cherish time", thus telling young people how to do it. In the stem of the question, it is required to talk about understanding in combination with the content of this article, so it is necessary to copy down the sentences that can reflect "learning" and "cherishing" in the article, so that the answer is complete.

Question 8: Who invented the soap flower? Is it poisonous? It is not clear who invented it. First of all, see if your soap flower is a three-no product, and check whether industrial dyes have been added. Industrial dyes are harmful to your health. .

Question 9: Who invented the detergent? Records show that soap may be made. As early as 2800 BC, it was recorded that both ancient Greeks and Romans began to make soap from olive oil in Nangang area. For many years, it was considered that the earliest soap making was a luxury, and only the richest individuals and families. Bankers make soap, hire their products and pay their rich and excellent employers. Because of its rare status, the consumption of handmade soap in previous years was accepted by everyone. However, one thing remains unchanged for many years, just like washing with soap at present.

Detergent, on the other hand, is the product of modern industry, and there is no clear record of who invented it.
