Question

The solubility of a solid in a liquid is significantly affected by temperature changes.

\[\ce{Solute + Solvent -> Solution}\]

The system being in a dynamic equilibrium must follow Le-chatelier’s principle.

Considering the Le-chatelier’s principle which of the following is correct?

Options

• ΔH_sol > 0; solubility ↑; temperature ↓

• ΔH_sol < 0; solubility ↓; temperature ↑

• ΔH_sol > 0; solubility ↓; temperature  ↑

• ΔH_sol < 0; solubility ↑; temperature ↓

Answer 1

ΔH_sol < 0; solubility ↓; temperature ↑
