Opis

This script was created as an auxiliary material for chemistry laboratory classes conducted at Warsaw University of Technology, Faculty of Building Services, Hydro and Environmental Engineering. The intent was to gather and present in the form of a prescript basic information on the principles of preparing and conducting chemical experiments. Script contains descriptions of elementary methods, apparatus and measurement. The script is designed for Environmental Engineering students, as didactic material for @Chemistry laboratory course.
