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 = KHX where P is the partial pressure of the gas; and X is the mole fraction of the gas in the solution and KH 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 02 causes climbers to become weak and make them unable to think clearly.
