(a) What mass of potassium chloride would be needed to form a saturated solution in 50 g of water at 298 K ? Given that solubility the salt is 46/100 g at this temperature.
(b) What will happen if this solution is cooled ?

Text Solution

Verified by Experts

(a) Mass of potassium chloride in 100 g of water in saturated solution = 46 g
Mass of potassium chloride in 50 g of water in saturated solution = `((46 g))/((100 g)) xx (50g) = 23 g`
(b) When the solution is cooled, the solubility of salt in water will decrease. This means that upon cooling, it will start separating from the solution in crystalline form.
