Question

F. State any one method to separate the following mixtures

1. two solid mixture on one which directly changes into vapour on heating
2. a solid liquid mixture containing an insoluble solid in the liquid component
3. a solid liquid mixture containing a soluble solid in the liquid component
4.a liquid liquid mixture containing two immiscible liquids having different densities
5. a liquid gas mixture containing a gas dissolved in a liquid component​

Answer 1

Answer:

1. Solvent extraction - The soluble solid dissolves in the solvent and the insoluble solid is left behind, and they are separated.

2. Sublimation - Sublimable solid changes into vapour on heating and the non-sublimable solid is left behind, and they are separated.

3. Filtration - insoluble solid is left behind in the filter.

4. Evaporation - The soluble solid is left behind while the liquid evaporates.
