Chemistry Experiments

Science and Humanities

There are numerous of materials used in fabricating and manufacturing devices for the comfort of life. The selection, characterization and suitability assessment of natural raw materials essentially requires principles and concepts of Applied Chemistry for technicians. This lab aims to supplement the factual knowledge gained in the lectures by first hand experiments. This will develop scientific temper and help to apply the basic concepts and principles in solving engineering problems.
