Organic Chemistry 

Qualitative Analysis

Separation and identification of solid binary mixture using water/NaHCO3 /NaOH and preparation of suitable derivatives.

Physical / Analytical  Chemistry     (Any three)

Colorimetry

1. Record an absorption spectrum of a substance (KMnO4/K2Cr2O7) using a spectrophotometer and determine absorption maxima (λmax).
2. 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.
3. Detection of adulteration of food stuffs - To detect the total dye content in sunset yellow colour
4. Water analysis- analysis of phosphorus in water.
5. Job’s method of continuous variation by iron-phenanthroline complex.
6. Mole Ratio method by iron-phenanthroline complex.

Polarimeter

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

Adsorption

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