MCQ

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

A
More solid will dissolve
✓
Some solid will precipitate out from the solution
C
The solution will become supersaturated
D
Solution concentration will remain unchanged

✓

Answer

Correct option: B.

Some solid will precipitate out from the solution

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