What is vapour pressure? And what is an ideal solution?
(N/A) Vapour pressure is the pressure exerted by the vapours of a liquid in equilibrium with the liquid at a given temperature.
An ideal solution is a solution that obeys Raoult's law over the entire range of concentration at all temperatures.
For an ideal solution,the enthalpy of mixing $(\Delta_{mix}H = 0)$ and the volume of mixing $(\Delta_{mix}V = 0)$ are zero.
