Question

12 g of saturated solution of potassium chloride at 20 o C . when evaporated to dryness . leaves a solid residue of 3 g. Calculate the solubility of KCl.

Answer 1

Mass of water in solution = (50 - 13.2) = 36.8 g

Solubility of KCl =

Massofwater

MassofKCl

×100=

36.8

13.2

×100=35.87g
