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,

All of these

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

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

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