A mixture of A and B in the molar ratio 1:2 forms a maximum boiling azeotrope. Identify the incorrect statement, if A is more volatile. [ Molar mass of A=100, Molar mass of B=50]

Answer»

A liquid solution of A and B having mass % of A=50 will have VAPOURS having mass % of A=50.
A liquid solution of A and B having mass % of ` Agt 50%` will have vapours having mass % of Agt50%.
A mixture of A and B in the molar mass ratio 1:3 can be seperated into azeotopic mixture and pure A
A mixture of A and B in the molar ratio 2:3 can be seperated into AZEOTROPIC mixture and pure A.
