Course Objectives:   

This course will enable the students to –

  1. acquire knowledge of conductometric titrations and their calculations. Make the students to get an insight on the use of apparatus used in volumetric analysis and correct titrimetric procedure along with standard and nonstandard solutions.
  2. perform all sorts of volumetric calculations. Acquaint students with the   identification of different functional groups and draw formulas and structures of these groups.
