Dissolution of sodium sulphate in water is exothermic (with evolution of heat). If the temperature is raised for a saturated solution of sodium sulphate, then according to Le-Chatelier principle

Question

Dissolution of sodium sulphate in water is exothermic (with evolution of heat). If the temperature is raised for a saturated solution of sodium sulphate, then according to Le-Chatelier principle (A) The solution will become supersaturated (B) Some solid will precipitate out from the solution (C) More solid will dissolve (D) Solution concentration will remain unchanged

When temperature increases precipitation of sodium sulphate takes place. Because reaction is exothermic so reverse reaction will take place.

Q. Dissolution of sodium sulphate in water is exothermic (with evolution of heat). If the temperature is raised for a saturated solution of sodium sulphate, then according to Le-Chatelier principle

The solution will become supersaturated

Some solid will precipitate out from the solution

More solid will dissolve

Solution concentration will remain unchanged

When temperature increases precipitation of sodium sulphate takes place. Because reaction is exothermic so reverse reaction will take place.
