Hours of instruction:

Weekly: two hours of lectures + one hour of exercises + four hours of labwork (2+1+4)

Goals:

The goal of this course is to help students acquire basic theoretical and practical knowledge of chemical and physical principles of analytical chemistry. Students will learn about the basic concepts regarding solutions, protolytic theory, buffers, dissolution and precipitation of ions and the basic concepts of oxidation and reduction. Additionally, the goal of the course is to help students acquire basic and applicable knowledge of classical quantitative chemical analysis by studying volumetric methods of analysis and gravimetry.

Outcome:

Upon completing this course, students are able to apply theoretical and practical knowledge of analytical chemistry in biochemical laboratory as independent researchers. Apart from that, students have the fundamental knowledge necessary for the further studies in the field of biochemistry.

Teaching methods:

Lectures and experimental exercises.
