Henry’s Law – Mathematical Formula, Affecting Factors, Applications and Limitations

What is Henry’s Law?

Henry’s law states that the concentration of a gas in a liquid is proportional to the partial pressure of the gas in the air. This law is based on the idea that a gas will dissolve in a liquid until the concentration of the gas in the liquid is the same as the concentration of the gas in the air.

What is Mole Fraction?

Mole fraction is the number of moles of a given species divided by the total number of moles in the mixture.

When Pressure is Constant?

When pressure is constant, the force exerted on a surface is equal in all directions. This results in a net force of zero and the object does not move.

Relation of Henry’s Law Constant with Temperature

Henry’s law constant (H) is the constant of proportionality that defines the relationship between the concentration of a gas in a solution and the partial pressure of that gas in equilibrium with the solution. The higher the temperature, the greater the kinetic energy of the molecules and the greater the gas solubility.

Factors affecting Henry’s Law Constant

The Henry’s law constant, K H , is a measure of how well a gas dissolves in a liquid. It is a function of the temperature and the pressure of the gas and the liquid.

The higher the temperature and the pressure, the more gas will dissolve in the liquid.

Graph Between Solubility and Pressure (for Gas in Liquid Solution) According to Henry’s Law

As the pressure on a gas dissolved in a liquid increases, the solubility of the gas also increases.
