Question

What is meant by aqueous tension?

Answer 1

Aqueous tension:

• “Pressure exerted by saturated water vapor present in the moist is called aqueous tension.”
• When the gas is accumulated over water, it is moist and comprises water vapor.
• The overall pressure of the gas exerted (${\mathrm{p}}_{\mathrm{Total}}$) is equal to the total of the partial pressure of the dry gas (${\mathrm{p}}_{\mathrm{dry}}$) and aqueous tension.
• It can be expressed as:

${\mathrm{p}}_{\mathrm{Total}}={\mathrm{p}}_{\mathrm{dry}}+\mathrm{Aqueous}\mathrm{tension}$
