COURSE DESCRIPTION

Course objectives

Course enrolment requirements and entry competences required for the course

The goal of course is to familiarize students with the mechanisms and equilibrium of homogenous and heterogeneous chemical reactions and their applications in analytical methods for determining process. Theoretical basis of kinetic methods of analysis will be explained.

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

1. Calculate and predict the acid-base titration curve. Apply acid-base titration based on theoretical predictions.
2. Explain the method of calculating pM values different parts of the EDTA titration curves, based on the application of knowledge of the equilibrium of complex formation.
3. Construct the redox titration curve and anticipate the possibility of using visual redox indicators based on theoretical predictions.
4. Define and apply the precipitation requirements.
5. Calculate and predict the precipitation titration curve.
6. Compare kinetic methods of analysis and classical analytical methods based on thermodynamic equilibrium, in terms of selectivity and application options.
7. Solve numerically analytical problems.

Grading and evaluating student work in class and at the final exam

Scoring at the exam consists of two basic parts, test of numerical example (minimum score: 18; maximum score: 30) and test of theoretical part (minimum score: 42; maximum score: 70).
Students who had attended lectures and seminar in 70 % can take the exam through partial tests: 2 tests of numerical examples (minimum score: 9; maximum score: 15) and 2 tests of theoretical part (minimum score: 21; maximum score: 35)
The rating is formed in accordance with the score ranges: sufficient ( 60 - 70 points) , good ( 71-80 points) , very good ( 81-90 points) , excellent ( ≥91points )

Quality assurance methods that ensure the acquisition of exit competences

Quality assurance will be performed at three levels:
(1) University Level; (2) Faculty Level by Quality Control Committee; (3) Lecturer’s Level.
