Question

State Henry's law.

Answer 1

Henry's Law:

Henry's law states that: The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid at constant temperature.

Mathematically: \[ C \propto P \quad \Rightarrow \quad C = k_H \cdot P \] where:

• \(C\) = concentration (or solubility) of the gas in the liquid
• \(P\) = partial pressure of the gas
• \(k_H\) = Henry’s law constant
