Question:
What is the significance of Henry’s Law constant KH?
Solution:
Henry’s law states that in a solution, “the partial pressure of the gas in the vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution”
The equation is given as p = KHx, where KH is the Henry Law’s constant. The constant is a function of the nature of the gas. If kH value is high at a given temperature, then lower will be the solubility of a gas in the liquid.
