Q.4 (a) State Henry’s law.
(b) Define : Osmotic pressure
Best answer
Answer: See (a) and (b) below.
(a) Henry's law: The solubility of a gas in a liquid at constant temperature is directly proportional to the pressure of the gas above the solution: \(S = K_H P\), where \(K_H\) is Henry's law constant.
(b) Osmotic pressure: The osmotic pressure of a solution is the excess hydrostatic pressure that must be applied on the solution side to just stop osmosis, i.e. the flow of solvent molecules into the solution through a semipermeable membrane. \(\pi = MRT\).
