Physical Chemistry     (Any four)                      

1. To determine the mutual solubility curve of phenol – water system and their consolute point.
2. To study the effect of a solute (NaCl/succinic acid) on the critical solution temperature of two partially miscible liquids (e.g. phenol-water system) and to determine the concentration of that solute in the system.
3. To determine the transition temperature of given substance by thermometric method.
4. Titration of acetic acid against NaOH pH metrically.
5. Determination of solubility and solubility product of sparingly soluble salt , silver chloride.
6. Determination of cell constant of a given cell.
