Question

Consider an ideal homogeneous liquid solution of methanol (a more volatile liquid) and water having vapour pressure of P mm Hg at 2 5 ∘ C . If P m o ​ and P w o ​ are the vapour pressures of pure methanol and pure water respectively at 2 5 ∘ C , then

TestHub · Accepted Answer

The vapour pressure of an ideal homogenous solution of two volatile liquids will always lie between the vapour pressures of pure components. In case of an ideal solution of methanol and water, the vapour pressure of solution (P) will be greater than P w o ​ but less than P m o ​ because P m o ​ is greater than P w o ​ (boiling point of methanol is lower than that of water).
