THEORY (45 Hours)

UNIT –I (11 Hours)
Dilute solutions: Lowering of vapour pressure, Raoult‘s and Henry‘s Law and their applications,
Excess thermodynamic functions, thermodynamic derivation using chemical potential to derive
relations between the four colligative properties (relative lowering in vapour pressure, elevation in
boiling point, depression in freezing point, osmotic pressure) and amount of solute. Applications
in calculating molar masses of normal, dissociated, and associated solutes in solution.
UNIT –II (12 Hours)

Solution and Interfacial Behaviour of Surfactants: Definition and classification of surfactants.
Solution properties of surfactants: micelle formation, critical micelle concentration (CMC),
dependence of CMC on chain length of the surfactant, micelle shape and size. Thermodynamics
of micelle formation, hydrophobic effect (a qualitative view only). Aggregation at high surfactant
concentration (a qualitative aspect) to micelles. Surface tension and detergent. Practical
application of surfactants.
