Question
In certain composition ranges of mixtures of ethylene tetrachloride (C2Cl4), isopropyl alcohol, and water separate, if given enough time, into two liquid phases. A table of eqilibirium data is shown below: The left-hand side of the table shows the compositions in the lower layer and the right-hand side shows the compositions of the upper layer in equilibrium with that composition. In the process for today, 100 lbs of a composition of 40%-by-mass C2Cl4, 38%-by-mass isopropyl alcohol and 22%-by-mass water is initially mixed and then allowed to separate.
| Lower | layer | %-by-mass | Upper | layer | %-by-mass |
| C2Cl4 | isopropyl alcohol | water | C2Cl4 | isopropyl alcohol | water |
| 100 | 0 | 0 | 0 | 0 | 100 |
| 94 | 5 | 1 | 1 | 33 | 66 |
| 88 | 10 | 2 | 21 | 49 | 30 |
| 82 | 15 | 3 | 35 | 46 | 19 |
| 76 | 20 | 4 | 20 | 38 | 12 |
