Mixtures can be separated into pure substances by applying appropriate separation techniques.

Techniques of separation are given below :

Filtration: Filtration is the process of separating a solid-state from any liquid by the filter. The filter only allows liquid substances but not any solid-state.

Decantation: Decantation is the technique of separating any two mixture of liquid by removing the top layer of any one substance.

• The common example of Decantation is oil and water, Vinegar, and water.

Distillation - Distillation is the method of separating a mixture of two substances (one liquid and one solid) by boiling.

Sublimation - The sublimation technique can be done in two solid substances. The sublimation is the process in which a solid-state directly changes into a gaseous state without going through the liquid state.

Melting: The process of conversion of solid-state to liquid sate is called melting or fusion.
