Which statement correctly describes solubility of gases in liquids?
Answer and explanation
Correct answer: Increasing temperature usually decreases gas solubility
The dissolution of a gas in a liquid is commonly exothermic, and heating generally increases the tendency of dissolved gas molecules to escape. Therefore gas solubility usually decreases as temperature rises. In contrast, increasing partial pressure generally increases gas solubility according to Henry's law. The words usually and generally allow for the fact that exact behaviour depends on the particular gas-solvent system.
