Course Contents/Syllabus:
List of Experiments (Any 10 Experiments are to be performed)
Colorimeter
1. Determination of pK value of an acid-base Indicator (Methyl red) using Colorimeter.
2. Simultaneous estimation of Mn2+ and Cr3+ in a solution of KMnO4 and K2Cr2O7.
3. Determination of concentration of ferrous ions in a given sample spectrophotometrically by Ophenanthroline method and by using KCNS as colour developing agent.
pH meter
1. To determine the acid and base dissociation constant of an amino acid using pH meter.
2. Determination of pH of number of solutions containing CH3COOH and CH3COONa and hence
dissociation constant of the acid
Preparation and Characterization
1. Preparation of Sodiumtetrathionate and interpretation of IR spectrum.
2. Preparation of Iron (II) oxalate and interpretation of its IR spectra.
Ultrasonic Interferometer
1. To determine the acoustical Parameters of a given Liquid. Determination of deviation in sound
velocity of binary liquid mixtures.
2.
Determination of apparent molal compressibility and partial molar compressibility of urea
and KCl/ NaCl/ Na2SO4/K2SO4 solutions using Ultrasonic Interferometer.
Refractometer
1.
To determine the refractive indices of series of solutions of KCl and hence the composition of
the unknown solution of the salt.
Dry Lab
1. Interpretation of UV-VIS, IR, NMR and Mass spectra of different compounds.
