Mass Transfer
When acetone is added in a two layer mixture of methyl isobutyl ketone and water at 30°C, the acetone distributes between the two layers and the composition of the layer follows two solubility curves. For this system,

Both the phases become identical at a particular common point on both the solubility curves called the plait point

The distribution curve which is a plot between x (acetone concentration in one phase) and y (acetone concentration in other phase) is analogous to x-y curve used in distillation and absorption termina

As the acetone concentration increases, the solubility curves approach each other

All of these
