Course Objectives:   

This course will enable the students to –

  1. Enable the students to 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 non standard solutions.
  2. Enable them to perform all sorts of volumetric calculations. Acquaint students with the identification of different functional groups and draw formulas and structures of these groups

(Practical)

 

The students will be able to –

 

CO36: inculcate the skills in the quantitative analysis by doing titrations in the different types of volumetric analysis and learn the principle difference between iodometric and iodimetric titrations

CO37: impart a thorough knowledge about the chemistry of some selected functional groups and classify organic compounds based on functional groups

CO38: develop skills required for the qualitative analysis of organic compounds, determination of melting and boiling points

CO39: interpret conductometric titrations and compose the curves for conductometric titration and determine the specific and equivalent conductance of the given electrolyte at different dilutions
