Question

Explain the solubility of gases in liquids.

Answer 1

1. Gases are soluble in water and other liquids and their solubility depends upon the nature of the gas.
2. In polar solvents, non-polar gases such as O₂ are less soluble.
3. Polar gases like CO₂, NH₃, HCl, etc. are more soluble in polar solvent like water. CO₂ forms H₂CO₃, while NH₃ forms NH₄OH in aqueous solutions.
4. Increased pressure and decreased temperature cause gases to become more soluble in liquids.
