Course objectives
Basic laboratory operations (filtration, crystallization, distillation, sublimation, volumetric methods) as well as determination of physicochemical constants of compounds are exercised in this course.
Students will learn in this course:
safety and fire rules and basic rules for safe chemical laboratory practice
physico-chemical measurements, operation with instruments, and evaluation of obtained data
to perform basic laboratory operations and manipulation with chemical laboratory equipment and simple instruments
to carry out more advanced laboratory experiments, data evaluation, construction of tables, graphs, and diagrams

Teaching methods
Laboratory course covers basic laboratory operations and writing laboratory reports.
Assessment methods
The laboratory course runs on a weekly basis. Each student is tested at the beginning of the class for the theoretical knowledge of the particular experiment by a short written test or by questions. All calculations for the particular experiment must be performed before the class. The absence at the class must be justified by a medical report. All missed classes must be made-up by the end of the semester. Requirements for passing the class:

a) attendance at all laboratory classes (missed classes must be made-up)

b) knowledge of principles of all experiments covered in the course, stoichiometric and concentration calculations and titration evaluation

c) careful preparation and timely submission of lab reports for all experiments

d) passed test from laboratory safety rules, calculations, and experiment principles

e) paid balance for broken glassware and equipment
