How many kilograms of potassium nitrate will crystallize from 100 kg of a solution saturated at 60C if its is cooled 0C? The solubility of potassium nitrate at 60C is 110 g at 0C is 13g in 100 g water.
Crystallization is based on the principles of solubility: compounds (solutes) tend to be more soluble in hot liquids (solvents) than they are in cold liquids. If a saturated hot solution is allowed to cool, the solute is no longer soluble in the solvent and forms crystals of pure compound.
The solution of the question kilograms of nitrate that will crystallize is as follows:
