Question
Assume that argon exerts a partial pressure of 6 bar. Calculate the solubility of argon gas in water. (Given Henry’s law constant for argon dissolved in water, KH = 40 k bar)

Solution
p = KHx
Mole fraction of argon in water x = `"p"/"k"`
= `6/40 × 10^3`
= 1.5 × 10–4

Why do gases always tend to be less soluble in liquids as the temperature is raised?
The air is a mixture of a number of gases. The major components are oxygen and nitrogen with approximate proportion of 20% is to 79% by volume at 298 K.
