[Summary of the course] In this course, following the Chemical Engineering and Industrial Chemistry Laboratories I a/b, basic experimental operations in physical chemistry and analytical chemistry will be instructed for the sophomore students in Department of Chemical Science and Engineering. The following three themes in these fields are set: (1) “Acid-base neutralization titration and acid dissociation constant” for learning the theoretical backgrounds of the experimental aspects of acid-base neutralization titration., (2) “Homogeneous catalytic reaction” for learning H2O2 degradation mechanism and kinetics in homogeneous solution containing catalyst, and (3) “Measurement of electrical conductivity” for learning the degree of dissociation for electrolyte solutions and the experimental methods. The lecture also covers how to write experimental reports.
[Aim of the course] To understand and acquire the basic concepts of physical chemistry, it is essential to perform experiments actually and to deeply consider the results obtained from the analysis of data. This course first covers fundamental operations and knowledge for physical and analytical chemistry along with how to write experimental reports. Following experiments of the three themes are designed to cultivate the practical skills of the students in measurements, analysis of data, and writing reports.
At the end of this course, students will be able to:
1) acquire the basic concepts of physical chemistry and analytical chemistry.
2) acquire basic techniques necessary for experiments in physical chemistry and analytical chemistry.
3) acquire how to write experimental reports.
(Acid-base neutralization titration and acid dissociation constant) Physico-chemical methods, Acid-base neutralization titration, Acid dissociation constant

|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
In this course, (1) details are explained and instructed in the first lecture. Then the students are divided into three groups to learn the following three experiments in turn: (2) Acid-base neutralization titration and acid dissociation constant, (3) Homogeneous catalytic reaction, and (4) Measurement of electrical conductivity. In the last day, exercise problems and interpretation of the answers will be given to assess the students' level of understanding.

Students will be assessed on their ability of fundamental experimental skills and achievements of learning outcomes based on the equality of reports on three themes (83%) and examination (17%).
The instructor may fail a student if he/she repeatedly comes to class late or does not submit assignments too often.
The prerequisite to take this course is that you have acquired the credits of "Chemical Engineering and Industrial Chemistry Laboratory I a/b".
Without having acquired the credits of the above course, the credits of this course will not be counted as the necessary number of credits for graduation.
Students must belong to Department of Chemical Science and Engineering or suffice the conditions given by the committee for the chemical engineering and industrial chemistry laboratory.
