Question

How does solubility of solid and gases solutes vary with temperature?​

Answer 1

12th/Chemistry

Solutions

Answer :

⧪ Effect of temperature on solubility of a solid in a liquid :

• If the dissolution process is endothermic (∆H > 0), the solubility increase with rise in temperature.
• If the dissolution process is exothermic (∆H < 0), the solubility decrease with rise in temperature$.$

⧪ Effect of temperature on solubility of a gas in a liquid :

• As dissolution is an exothermic process, then according to Le Chatelier's Principle, the solubility should decrease with increase of temperature.
