pragya makes a saturated solution of potassium chloride in water at 353K and leaves the solution to cool at room temperature. What would she observe as the solution cools? Explain
As solution cools, potassium chloride gets crystallized or precipitated. Because at 353K, solubility of potassium chloride is 54 g per 100 g of water. Whereas at room. temperature (20°C) it is 35 g. So excess of potassium chloride dissolved gets precipitated.
Answers & Comments
Answer:
as the solution cools the colours will turn from light blue to light blue
