What is Miscibility Gap?
A miscibility gap is a region in a phase diagram where two liquids (or solids) are not completely miscible and form two separate phases. Outside the miscibility gap, the components mix in all proportions; within the gap, they separate into two phases with different compositions. The miscibility gap is bounded by a binodal curve (equilibrium compositions) and, in liquid-liquid systems, a spinodal curve (limit of metastability).

Safety depends on specific system. Many immiscible liquid pairs involve organic solvents (toxic, flammable). Phase separation can lead to unexpected concentration of reactive species.
