States Of Matter

Question

Wired Faculty App

How is Dalton's law of partial pressures useful in calculating the pressure of a dry gas?

Solution

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:
P_{moist gas} = P_{dry gas} + P_{water vapours}
But pressure exerted by the water vapours is called aqueous tension. Thus,
P_{dry gas} = P_{moist gas} - Aqueous tension
