All of the above

Vedclass · Answer

(D) The Ostwald-Walker dynamic method is used to measure the relative lowering of vapour pressure,the lowering of vapour pressure,and the vapour pressure of the solvent. In this method,the apparatus consists of two sets of bulbs: the first set contains the solution and the second set contains the pure solvent. The loss of weight in the solution bulbs corresponds to the lowering of vapour pressure,while the total loss of weight in both sets of bulbs corresponds to the vapour pressure of the solvent. Thus,the relative lowering of vapour pressure is calculated as $\frac{	ext{lowering of vapour pressure}}{	ext{vapour pressure of solvent}}$.

Which of the following can be measured by the Ostwald-Walker dynamic method?
