Dear Keith and Tim,
Brine is normally used for breaking up an emulsion. If oil and water
phases have formed a strong emulsion they will not separate by keeping.
Addition of saturated salt solution increases the density of the aqueous
phase hence the difference between the densities of oil and water phases is
increased. As a result the emulsion breaks up. But this does not mean that
the oil phase is dry. Further drying is possible by stirring and heating
the oil at 110 C.
