1.	(a) On mixing liquid X and Y, the volume of the resulting solution increases. What type ofdeviation from Raoult's law is shown by the resulting solution ? What change in temperaturewould you observe after mixing X and Y ? (b)How can the direction of osmosis be reversed ? Write one use of reverse osmosis.
Answer» Solution :(a) The resulting solution will SHOW positive DEVIATION from Raoult.s law. A LOWER temperaturewill be observed. (b) We can reverse the DIRECTION of osmosis by applying a pressure greater than the OSMOTICPRESSURE on the solution. Reverse osmosis is used in the purification of water for domesticand commercial purpose.
