It is possible in principle for a binary liquid system to show more than one region of LLE for a particular temperature. For example, the solubility diagram might have two side-by-side “islands” of partial miscibility separated by a homogeneous phase. What would the ΔG vs. x₁ diagram at constant T look like for this case? Suggestion: See Fig. 12.13 for a mixture showing normal LLE behavior.
