Unit I: 

Organic Chemistry                                                                                40 hrs

Qualitative Analysis

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

 

Physical / Analytical Chemistry                                                               20 hrs

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.

e) Job’s method of continuous variation by iron-phenanthroline complex.

f)  Mole ratio method by iron-phenanthroline complex.

 

Polarimeter

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

 

Adsorption

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