Lowering of vapour pressure by Ostwald & Walker dynamic method. It is based on theprinciple when air is allowed to pass through a solvent or solution, it takes up solvent vapourwith it to get itself saturated at that temperature(I) & (II) are weighed separately before and after passing dry air. Loss in mass of each setgives the following of vapour pressure. The temperature of air, the solution and the solvent iskept constant
