Question
State Henry’s law and mention some important applications?
✓
Answer
The effect of pressure on the solubility of a gas in a liquid is governed by Henry's Law. It states that the solubility of a gas in a liquid at a given temperature is directly proportional to the partial pressure of the gas Mathematically, $P = K_HX$ where $P$ is the partial pressure of the gas; and $X$ is the mole fraction of the gas in the solution and $K_H$ is Henry's Law constant. Applications of Henry's law:
In the production of carbonated beverages $($as solubility of $C02$ increases at high pressure$).$
In the deep sea diving.
For climbers or people living at high altitudes, where low blood $0_2$ causes climbers to become weak and make them unable to think clearly.
