How is Dalton's law of partial pressures useful in calculating the pressure of a dry gas?
Gases like hydrogen, nitrogen, oxygen etc. which do not dissolve in water are collected over it. The pressure of the gas recorded is the pressure of the moist gas. The pressure of the dry gas can be calculated with the help of Dalton’s law of partial pressures. Mathematically:
Pmoist gas = Pdry gas + Pwater vapours
But pressure exerted by the water vapours is called aqueous tension. Thus,
Pdry gas = Pmoist gas - Aqueous tension
