Feed solution $\textbf{F}$ is contacted with solvent $\textbf{B}$ in an extraction process. Carrier liquid in the feed if $\textbf{A}$ and the solute is $\textbf{C}$. The ternary diagram depicting a single ideal stage extraction is given below. The dashed lines represent the tie-lines.
The $\text{CORRECT}$ option(s) is/are
- For the tie-lines shown, concentration of solute in the extract is higher than that in the raffinate
- Maximum amount of solvent is required if the mixture composition is at $W$
- $Y$ represents the composition of extract when minimum amount of solvent is used
- $U$ represents the raffinate composition if the mixture composition is at $M$
