12g of a saturated solution of potassium chloride at 20 Celsius, when evaporated to dryness, leaves a solid residue of 3g. Calculate the solubility of potassium chloride at 20 degrees Celsius.
Hello student,
I hope you are doing well.
Weight of Water in solution = 12g - 3g = 9g
9g of H2O dissolves 3g of solid
=> 100g of Water will dissolve
(3/9)X100 = 33.3g
=> Solubility of Potassium Chloride(KCl) at 20 degrees Celsius in H2O = 33.3g.
I hope you find it useful.
