State the principle involved in separation of solid-liquid mixtures by

1.	State the principle involved in separation of solid-liquid mixtures by – (a) sedimentation and decantation (b) filtration (c) evaporation
Answer» (a) Sedimentation and decantation — Principle — The solid component is insoluble and heavier than the liquid component. Example — Mixture of sand and water (b) Filtration — Principle — Seperation of insoluble solid component by passing through a porous material like filter paper. Example — Mixture of chalk and water, Mixture of Agcl and Water. (c) Evaporation — Principle — Seperation of the mixture by evaporating the liquid component. The solid should be soluble in the liquid and should not sublime.
