Vedclass · Answer

(B) The dissolution of sodium sulphate is an exothermic process,which can be represented as: $Na_2SO_4(s) + aq ightleftharpoons Na_2SO_4(aq) + 	ext{Heat}$.According to Le Chatelier's principle,if the temperature of an exothermic system at equilibrium is increased,the equilibrium will shift in the direction that absorbs the excess heat,which is the reverse direction.Therefore,the reverse reaction occurs,causing some of the dissolved $Na_2SO_4$ to precipitate out of the solution.

Sodium sulphate dissolves in water with the evolution of heat. Consider a saturated solution of sodium sulphate. If the temperature is raised,then according to Le Chatelier's principle:
