Physical Chemistry Experiments

Colorimetry

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

b) Mole Ratio method by iron-phenanthroline complex.

c) Record an absorption spectrum of a substance (KMnO4/K2Cr2O7) using a spectrophotometer

and determine absorption maxima (λmax).

d) 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.
