| Water, 93 per cent. |

| water, 8 per cent. |
| Aniline, 7 ,, | aniline, 92 ,, |
while the point k″ has the composition
Water, 69.9; phenol, 26.6; aniline, 3.5 per cent.
At 50°, the region of heterogeneous states now forms a band, and the two layers formed by water and aniline have the composition—
| Water, 96.5 per cent. |
| and |
| water, 5.5 per cent. |
| Aniline, 3.5 ,, | aniline, 94.5 ,, |
while the two layers formed by water and phenol have the composition—
| Water, 89 per cent. |
| and |
| water, 20 per cent. |
| Phenol, 11 ,, | phenol, 80 ,, |
All mixtures of water, phenol, and aniline, therefore, the composition of which is represented by any point within the band abcd, will form two ternary solutions; while if the composition is represented by a point outside the band, only one homogeneous solution will be produced.
3. The three components form three pairs of partially miscible liquids.
