Vedclass · Answer

(D) The solubility of most salts increases with an increase in temperature because the dissolution process is endothermic. However,for some salts like $Na_2SO_4$,the solubility decreases with an increase in temperature above $32.4 \ ^\circ C$ due to the transition from the decahydrate form to the anhydrous form,which is an exothermic process. According to Le Chatelier's principle,for an exothermic dissolution process,an increase in temperature shifts the equilibrium in the backward direction,thereby decreasing the solubility.

Identify from the following salts the one whose solubility in water decreases with an increase in temperature.
