A 44 kg liquid solvent stream containing 2 wt% acetic acid (A)and 98 wt% isopropyl ether (C) is used to extract a 63.8 kg feedsolution stream containing 31.32 wt% acetic acid (A) and 68.68 wt%water (B). This process is performed in a single-stagecounter-current extraction unit.
1) Identify the compositions (A and C) of mixture.
2) Plot the mixture point (M) on the diagram in this graphpaper.

3) Using the diagram in the graph paper, estimate thecompositions (A and C) of extract and raffinate using the trial anderror method. [HINT: The raffinate has anacetic acid composition in the range of 24.5 wt% to 26.5 wt%.]
4) Calculate the amount of extract and raffinate using the massbalance method.
