Which among following salts shows decrease in solubility with increase in temperature?

Options

ANa ₂ SO ₄
BKNO ₃
CNaNO ₃
DKBr

Correct answer

A. Na ₂ SO ₄

Step-by-step solution

Dissolution of Na ₂ SO ₄ in water is an exothermic process. When a substance dissolves in water by an exothermic process, its solubility decreases with an increase in temperature. Hence, solubility of Na ₂ SO ₄ in water decreases with increase in temperature.
