Solubility of Gas in Liquids

Henry’s Law in Solubility of Gas in Liquids:

• The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.
• This relationship is expressed by Henry’s Law:
  • • • • • $C = k_H \cdot$
• Where:
• C is the concentration of the gas in the liquid.
• k_H​ is Henry’s Law constant, which is specific to each gas-solvent pair.
• P is the partial pressure of the gas.

Factors Affecting Gas Solubility:

1. Pressure: Higher pressure increases gas solubility.
2. Temperature: Gas solubility typically decreases with increasing temperature.
3. Nature of Gas and Solvent: Gases with higher solubility in a particular solvent often have greater interactions (e.g., polar gases in polar solvents).
