UNIVERSITY OF LIBERIA COURSE CATALOG

DEPARTMENT OF CHEMISTRY
Degree of Bachelor of Science
in Chemistry Requirements

The course of study for the degree of Bachelor of Science in Chemistry takes four academic years. The minimum requirements for the degree are 135-136 semester hours. A candidate must complete his general education requirements of 51-52 semester hours as prescribed by the University of Liberia. He must earn fifty-two (52) semester hours in his major, eighteen (18) semester hours in his minor and thirteen (13) semester hours of supporting elective.

Course Description - Chemistry

101-102 Chemistry - General Chemistry

A general concept of the fundamental laws and theories of chemistry: gas laws and the laws of chemical combination : oxidation and reduction; solutions - kinds and properties; chemical kinetics, equilibria and thermodynamics; related problems. A study of non-metals, metals and their compounds; and a brief introduction to the fundamental ideas and the scope of organic chemistry.

The laboratory work includes experiments, the fundamental laws, rate of reactions, heat and reactions, neutralization, oxidation and reduction; preparation of selected elements and study of their properties; systematic separation and identification of cations and anions. Three hours lecture, one hour recitation, and three hours laboratory.
