(a) Ideal solution: Those solutions which follow Raoult's law at specific temperature over the entire range of concentration are called Ideal solution.
(b) Azeotrope: A liquid mixture which distills at constant temperature without under going any changes in composition is called Azeotrope.
(c) Osmotic pressure: The minimum excess pressure that has to be applied on the solution side to prevent the entry of the solvent into the solution through the semipermeable membrane is called osmotic pressure.
