In the case of immiscible liquids, the addition of one liquid to another does not after the properties of either liquid. Hence liquid exerts its own vapour pressure independently of the pressure of the other. Since boiling point of any system is the temperature at which its total vapour pressure becomes equal to the prevailing pressure, so by knowing the miscibility of two liquids, we can find out boiling temperature.
If we mix two immiscible liquids A and B then boiling point of the mixture will be (Given `p_(A)^(@) gt p_(B)^(@))`

Options

A. greater than `T_(B)` and lower than `T_(A)`
B. greater than either of `T_(A)` and `T_(B)`
C. lower than `T_(B)` and higher than `T_(A)`
D. lower than either of `T_(A)` and `T_(B)`

Answer

D

Explanation

Liquid will boil when
`p_(A)^(@)+p_(B)^(@)=` Atmospheric pressure.
