1) State and explain Henry's law.? ans) Henry’s law states that at constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas. Mathematically, p = KH.χ (where p is the partial pressure, χ is the mole fraction and KH is the Henry’s law constant). 2) what are colligative properties? ans) These are properties which depend only on the number of solute particles and not on their nature. 3) what is meant by osmotic Pressure? ans) It is the excess pressure that must be applied on the solution side to prevent osmosis. 4) What is reverse osmosis? Write any one of its applications.? ans) : It is the process of flow of solvent molecules from solution side to solvent side through a semi permeable membrane (SPM), when a pressure greater than osmotic pressure is applied on the solution side. [OR, If a pressure larger than the osmotic pressure is applied to the solution side, the direction of osmos...
