JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives

The course consists of experiments related to the principles of chemistry required

for engineering student. The student will learn:

• Estimation of hardness of water to check its suitability for drinking purpose.
• Students are able to perform estimations of acids and bases using conductometry, potentiometry and pH metry methods.
• Students will learn to prepare polymers such as Bakelite and nylon-6 in the laboratory.
• Students will learn skills related to the lubricant properties such as saponification value, surface tension and viscosity of oils.

Course Outcomes

The experiments will make the student gain skills on:

• Determination of parameters like hardness of water and rate of corrosion of mild steel in various conditions.
• Able to perform methods such as conductometry, potentiometry and pH metry in order to find out the concentrations or equivalence points of acids and bases.
• Students are able to prepare polymers like bakelite and nylon-6.
• Estimations saponification value, surface tension and viscosity of lubricant oils.
