20.00 HRS

Physical / Analytical  Chemistry     (Any three)

Colorimetry

a) Record an absorption spectrum of a substance (KMnO4/K2Cr2O7) using a spectrophotometer and determine absorption maxima (λmax).

b) To verify the Beer-Lambert law for a compound( Potassium permanganate, copper sulphate, methylene blue etc. ) and determine the concentration of the substance using calibration curve.

c) Detection of adulteration of food stuffs - To detect the total dye content in sunset yellow colour

d) Water analysis- analysis of phosphorus in water.

Colorimetry

1. Job’s method of continuous variation by iron-phenanthroline complex.
2. Mole Ratio method by iron-phenanthroline complex.

Polarimeter

   c) To determine the specific rotation /unknown concentration of an    optically active compound (glucose/sucrose)

 Adsorption (Practice Exercise)

d) To study the adsorption of a solute (Acetic acid) on a dispersed solid (activated charcoal).
