Solubility diagram of two partially miscible liquids
A number of different mixtures of phenol and water are prepared and heated until complete miscibility is achieved. As the mixtures cool, two-phase systems form at certain temperatures which are recognisable by the appearance of turbidity. Plotting separation temperatures against compositions of the mixtures gives the separation curve.
- Good and reproducible results due to temperature control in the experiment.
