Course Objective: This course deals with the basic concepts of engineering chemistry which are
essential for engineering students of all branches. At the end of this course, a student will be
familiar with the basic principles involved in treatment of water, corrosion and its control,
lubricants and cementing materials. In Addition, the students will also learn the concept of
chemical bonding, analytical chemistry and chemistry of compounds resulting from
environmental pollution.
