Question

Pragya makes a saturated solution of potassium chloride in water at 353 K and leaves the solution to cool at room temperature. What would she observe as the solution cools? Explain. Pragya tested the solubility of three different substances at different temperatures and collected the data as given below (results are given in the given table, as grams of substance dissolved in 100 grams of water to form a saturated solution).

Answer 1

Answer: She would observe that the solution of pottasium nitrate gets cool and surpassed.

Explanation: This is because when the temperature rises then the solubility of the salt also rises and when it get cools or loses its temperature it gets surpassed from the line that was in 353 K.
