The general chemistry laboratory is designed to support and illustrate those concepts studied in the lecture part of the course, as well as to introduce the important laboratory techniques and encourage analytical thinking. Along with the concepts and chemistry covered in lectures, the laboratory portion of the course will present some additional chemistry including both theoretical and practical aspect. A number of basic chemistry experiments related to the development of skills in metric system, identification of substances by their properties, the law of definite proportions, basic separation techniques, stoichiometry of reactions, illustration of gas laws and electrochemistry and thermochemistry are done in general chemistry laboratories.
