Answer 2

1. By Sublimation: The process of conversion of solid directly into gaseous state and back to solid without passing through the liquid state.Sublimable solid changes into vapour on heating and the non-sublimable solid is left behind, and they are separated.
2. Evaporation: Evaporation is the process of conversion of liquid component to its gaseous state by heating. In a salt solution, water evaporates on heating and salt crystals are left behind in the dish.
3. By distillation- The process of separating two liquids by heating and converting into vapour in a distillation flask and its condensation of the vapour back into the liquid.
4. By separating funnel- The method used to separate two immiscible liquids, out of which one is heavy and the other is light.
5. By fractional distillation- The process of separating two miscible liquids with different boiling points.
6. By chromatography- It is a method of separating the various components of a mixture by their difference in rate of flow over an absorbent medium.
