What is meant by aqueous tension ? How is the pressure exerted by a gas corrected to account for aqueous tension?

Open in App

Solution

Aqueous tension is the pressure exerted by the saturated water vapour.All gasesare generally collected over the water as they are moist. ... Hence, Pressure of drygas = Pressure of moist gas - aqueous tension
