Define Henry's law about solubility of a gas in a liquid.

Solution

Henry's law: at a constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the surface of the liquid.
In terms of mole fraction:

p = K_{H} x

where

p

is the partial pressure of the gas,

x

its mole fraction in solution and

K_{H}

is Henry's law constant.
