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.
