Separation of mixture of two or more liquid
Separation of mixture of two or more liquid All the mixtures containing two (or more) liquids can be separated by the following two methods: (i) By the process of fractional distillation. (ii) By using a separating funnel. (A) Miscible liquids : Those liquids which mix together in all proportions and form a single layer are called miscible liquids. Example. Alcohol and water are miscible liquids because they mix together in all proportions and form a single layer on mixing. A mixture of miscible liquids is separated by the process of fractional distillation. (B) Immiscible liquids : Those liquids which do not mix with each other and form separate layers are called immiscible liquids. Example. Oil and water are immiscible liquids because they do not mix with each other., and form separate layers on mixing. Water being heavier forms the lower layer, and oil being lighter forms the upper layer. A mixture of immiscible liquids is separated by using an apparatus called separating funnel.
