Immiscible liquids. Oil and water can be separated using a funnel. Immiscible means that the liquids don't dissolve in each other â oil and water are an example. It is possible to shake up the liquids and get them to mix but they soon separate. Separating immiscible liquids is done simply using a separating funnel. The two liquids are put into the funnel and are left for a short time to settle out and form two layers.
Filtration, evaporation, crystallisation and drying are four techniques used in the isolation and purification of a solid product from a chemical reaction e.g. How can we separate a mixture of sand and salt? or, how do we separate a salt from a salt preparation?onsequently on cooling a hot concentrated solution, crystals form as the solubility gets less and less and the solubility limit is exceeded, so crystals must form. Crystallisation is also an important purification method because trace impurities tend to stay in solution.
