Question

What is the process based upon Henry's law?

Answer 1

Henry's law

• According to Henry's law, “ the partial pressure of the gas in the vapor phase $\left(p\right)$ is proportional to the mole fraction of the gas $\left(x\right)$ in the solution”.
• The mathematical relationship is as follows:

$p=K_{\mathrm{H}}\mathit{}x$

• Where, $p$ is the partial pressure of the gas, $x$ is the concentration of the dissolved gas, and $K_{\mathrm{H}}$ is Henry’s law constant.

Application of Henry's law:

• Soda cans are packed under high pressure in order to increase the solubility of the gas.
• The oxygen gas dissolves in the blood vessels is directly proportional to the partial pressure of oxygen in the lungs.
