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

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

All of the above

✅ The correct answer is option D.

171. The expression, y(1 – x)/x(1 – y) is for
