Students experiments

Although studying fundamental theories of chemistry in the class is important to understand the concept of chemistry, carrying out experiments to corroborate the theories is also important. It is very important for students to get used to experiments in order to speed up their experiments.

Students perform experiments in their second year in Practical Applied Chemistry I and in the third year in Practical Applied Chemistry II, as preparation for the graduate research carried out in the fourth year. Students acquire a knowledge of experiments (laboratory rules, how to record experimental results, how to analyze the results of experiments and how to carry out experiments safely), rather than learning experimental results in Practical Applied Chemistry I. Students acquire a relatively high level of knowledge in chemistry and experiment skills in Practical Applied Chemistry II.

Practical Applied Chemistry I

Study is divided into a beginner's course, a fundamentals course and an applied chemistry course. In the beginner's course, students study points to be noted in experiments by watching videos of experiments and do glasswork.

Glasswork is the basic skill of experimentation.

The fundamentals course and the applied chemistry course are divided into three sub-courses: physical chemistry, organic chemistry, and inorganic and analytical chemistry. In physical chemistry, students measure surface tension, densities and mutual solubilities of liquids. Students carry out organic qualitative analysis (ignition test, detection of halogen using Beilstein's test, detection of halogen and nitrogen using Lassaigne's test) in organic chemistry. In inorganic and analytical chemistry, students carry out qualitative analysis of positive ions.
