Summary of Experimental Report on Organic Chemistry for College Students
How to write an experimental report on organic chemistry? Experimental report is a written report that records the purpose, method, process and result of the experiment and then arranges it. Let's take a look at five short articles summarized in the experimental report of organic chemistry for college students, hoping to help you.

Organic chemistry experiment report 1

Through these five organic chemistry experiments this semester, I am more familiar with the basic operations of organic chemistry experiments, such as water bath heating, distillation, condensation, reflux and so on. Understand the experimental methods and principles of various drugs, and understand the safety rules of experiments to check the handling methods of accidents; The reporting requirements of organic chemistry experiments are clarified.

We have a better understanding of a series of organic chemical reactions that we have never been exposed to before. In the actual experiment, we have a deeper understanding of the knowledge in books. For example, we need to remove impurities from various reaction by-products. We also know that organic reactions are generally slow, and we need to heat or add catalysts to speed up the reaction. We also have a better understanding of the use of various new instruments and equipment. Of course, some mistakes will inevitably occur in the experiment. Through the analysis of these mistakes, we can further improve ourselves and improve our experimental skills in organic chemistry experiments. Only by improving your skills can you further discover more mysteries behind the experiment in the future, and only by your own efforts can you make your own innovations.

I believe that through these five organic chemistry experiments, we will master more experimental skills and lay the foundation for more complicated experimental operations in the future. At the same time, analyzing our own mistakes in operation can also deepen our understanding of the experiment and avoid making mistakes again. At the same time, we are ready for the experiment next semester, which adds some strength to our chemistry study and increases our interest in continuing to study and confidence in learning chemistry well.

Experimental report on organic chemistry II

Analytical chemistry is a practical subject. The task of analytical chemistry experiment course is to further deepen our understanding of the basic theory of analytical chemistry. Correctly master the basic operation skills of analytical chemistry experiments. Cultivate good experimental habits and rigorous and realistic scientific attitude, and improve the ability to observe, analyze and solve problems. To lay a good foundation for future study of follow-up courses and practical work.

Experiment is the soul of chemistry, the charm of chemistry, the main source to stimulate students' interest in learning, and an important method and means to cultivate and develop students' thinking ability and innovation ability. The significance of analytical chemistry experiment lies in the following points: first, analytical chemistry experiment can improve learning interest. Secondly, analytical chemistry experiments can cultivate our observation ability. Finally, experiments can cultivate our thinking ability.

During my summer internship as a freshman, I made a survey of drinking water quality in Beijing with the Association for Science and Technology of University Students. That activity was my first systematic experiment in analytical chemistry. The following are my summaries of that activity.

The purpose of the activity is not only to cultivate the analytical chemistry experiment ability of the members of the Association for Science and Technology, but also to let the members experience the steps of more formal scientific research projects-discussion, topic selection, sampling and analysis ... Through this activity, the members of the Association for Science and Technology will be more capable and confident to plan when they are faced with topics involving foreign majors or whose academic level is difficult to reach at present. Investigation is an extension of the traditional activity of the Students' Association for Science and Technology-Chemical Experiment Skills Competition. Chemical experiment skills are organically dissolved in the hydraulic measurement stage of investigation, which raises simple experiments to the height of scientific research.

From the sampling stage of the survey, all members fully participated in the activities. The sampling range is the drinking water of residents in eight districts of Beijing. In principle, each city has two water samples. I was assigned to Chaoyang District to collect water samples. Chaoyang District is a large area in Beijing. My residential area is Jingang International, a newly developed building located at Xidawang Road 19. Located in Pan-CBD, it is also a popular place to enter the market recently. The residential area I choose is a white-collar apartment, with pure tap water pipes and a complete final water system besides tap water. I collected a pure water sample and a tap water sample in this community for comparison.

In the experimental stage, members who have not studied analytical chemistry can contact some high-precision instruments in advance, such as analytical balance. This will have a great positive impact on freshmen's future study. Although mistakes often occur because of the unskilled use of experimental instruments, we finally get more accurate experimental data because of the serious attitude of the participants. Among the two water samples I collected, the water hardness level of tap water samples in this community is similar to the average water hardness level of tap water samples in other urban areas. The water hardness of pure water is almost three times that of tap water, and the PH value is weakly acidic, which proves that the pure water sample supplied to this room contains more ions. Due to the limitation of experimental conditions and professional knowledge, we can't detect the ions contained in water samples one by one, but it is enough to prove that the so-called pure water samples are not as pure as we usually understand. As the water samples were collected at home, we were unable to get water samples from this pure water source. Considering that the pipeline in the new house may be unusable and the water sample is greatly influenced by the pipeline material, the bad water sample collected this time cannot be judged as impure water source.

From the first contact with analytical chemistry experiment to now, after a semester of study and practice, I found that doing analytical chemistry experiment well needs to do the following five things:

First of all, we should do a good preview. You should read the relevant basic theoretical knowledge carefully before the experiment. Understand the required basic operation technology, and make clear the experimental purpose, principle, task, main operation steps and related matters, so as to be prepared.

Second, during the experiment, carefully consider the purpose and function of each step, carefully observe the experimental phenomenon, and integrate theory with practice. In the experiment, all kinds of original data measured in the experiment are recorded on the original experimental record paper at any time, which is true, accurate and clear, and is convenient for teachers to review.

Third, strictly abide by the operating procedures and precautions. Before using unfamiliar instruments and reagents, do not operate them at will, so as to avoid damaging experimental instruments, wasting reagents and causing accidents.

Fourth, consciously abide by the operating procedures and precautions. Pay attention to power supply, electric furnace, water valve, etc. Clean the instrument in time after the experiment.

Fifth, after the experiment, the original data are sorted, calculated and analyzed. Summarize experimental experience, analyze and think about problems wrongly, etc.

The formation and development of chemical science can not be separated from experiments. Analytical chemistry experiment can help us to form chemical concepts, understand and consolidate chemical knowledge, master experimental skills, broaden our knowledge and cultivate our abilities of observation, thinking, experiment and inquiry.

Experimental report on organic chemistry 4

Chemistry is a course based on experiments and closely related to life and production. Chemical knowledge is very practical, so experiments are very important.

At the beginning of the experiment, due to the poor theoretical knowledge foundation of students, many problems were encountered in the experiment process, which also made students feel the importance of theoretical knowledge. Let students find problems in experiments, read books by themselves, think independently, and finally solve problems, so as to deepen students' understanding of textbook theoretical knowledge and achieve a "win-win" effect.

Before doing the experiment, you must thoroughly understand the knowledge in the textbook, because this is the basis of doing the experiment, and it is also the preparation of theoretical knowledge before doing the experiment, that is, you must know the relevant information of the experiment to be done in advance, such as the experimental requirements, experimental contents, experimental steps, and the most important thing is to record the experimental phenomena. Otherwise, the teacher will not understand when explaining, which will increase the difficulty of doing experiments and waste valuable time. For example, in the experiment of preparing chlorine by electrolysis of saturated salt solution, it is necessary to know the connection of various experimental instruments. If not, then explore when doing experiments, which will greatly waste your time and get twice the result with half the effort.

Although the teacher will explain the experimental steps when doing the experiment, it will be difficult to do it if you don't have some basic knowledge. You can only do what the teacher says, but you don't know what to do. When doing the experiment, you must do it yourself. You must explain every step and detail clearly. After the experiment, you must look back and think. Only in this way can you be impressed and remember. Otherwise, it will soon be forgotten. Might as well not do it. When doing experiments, teachers will teach students some knowledge that is not in textbooks according to their own personal experience, broaden their horizons and let them know.

Students should not follow other people's advice when doing experiments. They should have their own opinions, so they should be fully prepared. If they don't know what an experiment is, they will be in vain. Experiments are always related to textbook knowledge. In the process of experiment, we should try our best to reduce the blindness of operation and improve the guarantee of experimental efficiency. Some people rush to do it at first, but the more they do it, the busier they get. This is the main reason.

When doing the experiment, I didn't know the experimental steps carefully at first, but I was busy connecting the experimental instruments and adding drugs. As a result, the experiment failed and I finally had to ask other students for help. Especially when making an experimental report, because there are many problems in the experimental phenomenon, it is difficult to continue if it is not solved. If you have questions you don't understand, you can discuss them with each other and ask the teacher.

We should do experiments in the spirit of improvement and innovation, rather than sticking to the rules. In fact, on the basis of understanding the experimental principle, we should have enough time to do experiments with ease. If innovation is difficult for us, improvement is always possible. For example, in the experiment of the reaction between copper and concentrated sulfuric acid, we can improve the experiment through a self-made device.

In the process of experiment, we should cultivate students' ability to analyze and solve problems independently. The premise of cultivating this ability is students' attitude towards each experiment. If students do experiments casually, waiting for the teacher to teach them how to do it and copy their classmates' reports, although their grades will be high, it will be detrimental to their future work.

During the experiment, students' ability to study, analyze and solve problems in practice, as well as good inquiry ability and scientific ethics, such as team spirit, communication ability, independent thinking and the ability to capture the frontier information of the experiment, etc. Improve students' practical ability, cultivate the style of integrating theory with practice, and enhance the sense of innovation.
