Knowledge of secondary school chemistry and basic mathematics.

Rules for evaluation and completion of the course

The laboratory notebook (control of preparation), report sheets, tests, style of the work, course-unit credit test.
Evaluation of the test: excellent [100%-90%], very good [89%-80%], good [79%-70%], satisfactory [69%-60%], sufficient [59%-50%], failed [49%-0%]
The average from the evalution of the report sheets, of the tests, of the final test and style of the work is the final evalution of the course.
The attendance is compulsory. In the case of illness confirmed with a doctor is substitution in other students group possible.

Aims

The target of the course is an acquisition of laboratory knowledge of the starting students - chemists.
Obtaining skills and a practical knowledge of basic operations that are used in the chemical laboratory.
