Question:
The pressure exerted by saturated water vapour is called aqueous tension. What correction term will you apply to the total pressure to obtain a pressure of dry gas?
Solution:
The total pressure of the gas is Pmoist gas = Pdry gas
By applying the correction term,
Pdry gas = Pmoist gas – Aqueous tension
Therefore, the correction term applied to the total pressure of the gas to get the pressure of dry gas is P moist gas – aqueous tension
