If a saturated solution of potassium chloride in 200g of water at 75 degrees Celsius is cooled to 10 degrees Celsius approximately how many grams of solute will crystallize out of solution

Accepted Answer

The solubility of potassium chloride in water at 75 degrees Celsius is 43.1 g/100 g of water, while at 10 degrees Celsius it is 34.1 g/100 g of water. Therefore, when the solution is cooled to 10 degrees Celsius, 43.1 g - 34.1 g = 9 g of potassium chloride will crystallize out of solution.
