Question

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

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

Answer 1

The correct option is A More solid will dissolve

According to le chatelier principal if temperature is increased in exothermic reaction then reaction will go in that direction where temperature get decreased that is in backward direction so in case of reaction of Sodium sulphate dissolved in water reaction goes in more formation of sodium sulphate (solid ) i e in backward direction.
