Question

Name a substance whose solubility increases rapidly with temperature.

Answer 1

• Solubility is the new bond formation between the solute molecules and solvent molecules.
• In terms of quantity, solubility is the maximum concentration of solute that dissolves in a known concentration of solvent at a given temperature.
• Solubility often depends on temperature and this solubility increases with increasing temperature.
• Many salts show a large increase in solubility with temperature but it is not uniform.
• Potassium nitrate ${\mathrm{KNO}}_3$ is a substance whose solubility increases rapidly with temperature.
