Course Objectives: The course consists of experiments related to the principles of chemistry required for engineering student. The student will learn:

  • Estimation of hardness and chloride content in water to check its suitability for drinking purpose.
  • To determine the rate constant of reactions from concentrations as an function of time.
  • The measurement of physical properties like adsorption and viscosity.
  • To synthesize the drug molecules and check the purity of organic molecules by thin layer chromatographic (TLC) technique.

Course Outcomes: The experiments will make the student gain skills on:

  • Determination of parameters like hardness and chloride content in water.
  • Estimation of rate constant of a reaction from concentration – time relationships.
  • Determination of physical properties like adsorption and viscosity.
  • Calculation of Rf values of some organic molecules by TLC technique.
