Expression P=P1 = x1Pi (P is total vapour pressure) holds good for binary solution containing
CHCl3 and CH2Cl2
Nacl and H2O
MeOH and H2O
EtOH and CH3COCH3
As learnt in
Rault's Law -
The total vapour pressure of binary mixture of miscible liquids be having ideally is given by
Where and are mole fraction of A and B in liquid phase.
and are vapour pressures of pure liquids.
The expression given in Raoult's law but it is only valid for liquids that do not interact.
Only NaCl and H2O fulfill that condition.
