A batch of 1,000 kg of KCl is dissolved in enough water to create a saturated solution at 363 K, where the solubility is 35 wt percent KCl in water. The solution is cooled to 293 K, at what temperature its solubility is 25.4% by weight. a) How much water in weight is needed for the the solution, and how much KCl crystals weight were attained? b) If 5% of the initial water evaporates during cooling, what is the weight of crystals obtained?
