Question

A mixture of two liquids A and B having boiling point of A is 70° C, and boiling point of B is 100° C, distills at 101.2 ° C as single liquid, hence this mixture is (A) Ideal solution (B) Non ideal solution showing +ve deviation (C) Non ideal solution showing -ve deviation (D) Immiscible solution

Tardigrade Admin · Accepted Answer

A=70° C B=100° C distils at 101.2° C i.e., B.P of solution is greater than A / B and it shows maximum boiling Azeotrope means negative deviation [Vapour pressure of this solution is decreased]

Q. A mixture of two liquids $A$ and $B$ having boiling point of $A$ is $7 0^{\circ} C$ , and boiling point of $B$ is $10 0^{\circ} C$ , distills at 101.2 $^{\circ} C$ as single liquid, hence this mixture is

Ideal solution

Non ideal solution showing +ve deviation

Non ideal solution showing -ve deviation

Immiscible solution

$A = 7 0^{\circ} C$
$B = 10 0^{\circ} C$
distils at $101. 2^{\circ} C$ i.e., B.P of solution is greater than $A / B$
and it shows maximum boiling Azeotrope means negative deviation
[Vapour pressure of this solution is decreased]

Q. A mixture of two liquids A and B having boiling point of A is 70∘C, and boiling point of B is 100∘C, distills at 101.2 ∘C as single liquid, hence this mixture is
