Question

2. Explain at the molecular level why this relationship exists between temperature and solubility.

please answer any general answer.

Answer 1

Generally solubility increases with temperature.

With increasing temperature kinetic energy of the solvent molecule increases hence the molecules move far apart and create void thus give space for the solute molecules between solvent molecules. The extra energy also allows the solvent molecule to break the intermolecular forces in solute molecules easily .
