At constant temperature, 2 litres aqueous solution of each 0.2 M kcl and 0.3 M AlCl3 are in contact with each other by semipermeable membrane. When osmosis stops, then, what mililitre water diffuses from semipermeable membrane to the other side ? (Assume that ionic solids dissociates completely in the aqueous solution)
(a) 500 ml
(b) 600 ml
(c) 800 ml
