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 ?

A. As the acetone concentration increases, the solubility curves approach each other
B. Both the phases become identical at a particular common point on both the solubility curves
called the plait point
C. 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 terminates on the x = y diagonal at the concentration of the plait point
D. All A., B. and C.
