Answer: KCl would start precipitating.
Explanation: Potassium chloride on being dissolved in water absorbs heat from its surroundings.Therefore, dissolution of potassium chloride is an endothermic process.
The forward reaction is endothermic and thus the backward reaction is exothermic. According to Le Chatelier's principle, if the temperature is decreased , the reaction will shift in a direction in which the temperature is increasing i.e. backward direction.
The solubility of salt would decrease on decreasing the temperature.Thus KCl would start precipitating.
It's not a sufficient answer friend,,,first read and then Answer,, ,,,,,,,,ok
