Chemical Experiment1
This class is a chemistry practice for first-year students in the Department of Applied Chemistry. Chemistry is a study for
describing, explaining, and predicting phenomena in the real world, and is supported by "experiments" for observing and measuring
phenomena in the real world. Therefore, experiments account for a very large proportion of chemistry studies at universities.
Various preparations are required to carry out the experiment. It is necessary to learn the knowledge and know-how to carry out experiments safely. It is also necessary to gain experience in handling experimental equipment and instruments. It is also necessary to learn how to handle measurement data and how to describe and consider experimental results. The purpose of this class is to solidify these basics.
It is also an important purpose of this class to deepen the understanding of the laws and principles that govern chemical reactions through experiments. The themes taken up in the experiments are all important as the basis of chemistry. Try not only to handle the given menu mechanically, but also to deeply understand the observed phenomenon.
This class consists of experiments and exercises using a PC. In the experiment, we will first work on the phylogenetic analysis of cations, which is the basis of inorganic qualitative analytical chemistry. Next, we will perform quantitative measurements that are the basis of physical chemistry and inorganic chemistry, such as measurement of Avogadro constant, absorption analysis, measurement of molecular weight, and determination of acid dissociation index. We also conduct experiments that form the basis of organic synthesis. In the exercise, you will learn how to use the chemical structural formula drawing software ChemDraw and the spreadsheet software Excel using a PC.

The purpose of this class is to lay the foundations so that experiments that are important in advancing chemistry studies
can be carried out safely and efficiently, and that the experiments will be fruitful.
Through this class, you will be able to acquire the knowledge and know-how necessary to conduct chemical experiments safely. You can also learn the basic experimental operations of chemical experiments. You will also learn how to handle and display measurement data. You can also learn how to use ChemDraw, a chemical structural formula drawing software, and Excel, a spreadsheet software, which are indispensable tools for chemistry research. You will be trained in daily experimental guidance and report interview guidance so that you can talk about the observed and measured experimental results in the language of chemistry (science). In addition, compiling the results of the experiment into a report and taking an oral examination will also improve general communication skills and presentation skills.
