Course overview and goals
[Description]
Students will gain an understanding of the basic knowledge of inorganic and analytical chemistry through experiments, while also learning the basics of running chemical experiments and an experimental approach conscious of environmental safety. This course includes following experiments:
(1) Synthesis of complex salts and double salts to acquire the basics of running chemical experiments such as weighing, maturing, filtration, and recrystallization
(2) Titration experiments of oxidation-reduction and neutralization to learn how to prepare solutions and quantitation techniques
(3) Separation of ionic species by chromatography
(4) Spectroscopy and gravimetric analysis to learn quantitation methods of chemical species
[Aims]
Through the synthetic experiments of complex salts and double salts, students will acquire the basics of running experiments such as filtration, recrystallization, and maturing. From the titration experiments of oxidation-reduction and neutralization, they will learn how to prepare solution samples and how to quantify chemical species. They will also experience the separation of ionic species by chromatography and absorption spectrophotometry. These experiences are important as fundamentals of running more advanced chemical experiments.
Course description and aims
Students will acquire the following skills through this experiment course.
1) Basic knowledge of the various subfields of chemistry
2) Basics of running a chemistry experiment
3) Knowledge needed for safely running a chemistry experiment
4) Experimental approach conscious of environmental safety
5) How to write a precise description of running an experiment, and a lab report
Keywords
Complex salt, Double salt, Chromatography, Spectroscopic analysis, Oxidation-reduction titration, Neutralization titration, Gravimetric analysis
Competencies
- Specialist skills
- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
Class flow
One to three classes will be used for each topic, and students will run experiments on a total of 7 topics. Students must read the textbook in preparation before each experiment topic, and understand how to actually run the experiment and its meaning. After students complete an experiment, they will submit a report that summarizes the significance of the experiment, as well as the procedure, results, and observations.

Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 50 minutes preparing for class and another 50 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Textbook(s)
Textbook: "Experiments for inorganic and analytical chemistry", Hand out materials as needed.
Reference books, course materials, etc.
