Significance of Henry’s Law constant KH:
Henry’s law states that in the solution, “the pressure in the gas component at the vapor fraction (p) is equal to the fraction of the gas molecule (x) in solution”. The calculation is given as p = KHx, where KH is always Henry Law. Constant is a function of the gas type. If the kH value is high at a given temperature, then the decrease can be the dissolution of gas in a liquid.
