Question

A common method of separating an insoluble solid from a liquid from a liquid is known as :
A. Distillation
B. Filtration
C. Evaporation
D. Sublimation

Answer 1

Hint: We know that filtration, sublimation, evaporation and distillation are examples of separation techniques through physical change. Insoluble solids are the substances which do not dissolve in a given solvent or liquid even after mixing.

Complete step by step solution:
We know that sublimation is a process in which a solid directly transforms to gas or a gas directly transforms to its solid form . Only some special types of substances undergo sublimation . Evaporation is the process in which a particular liquid is transformed into its gaseous state by heating it . Distillation is the process in which we separate a mixture of two liquids which have different boiling points. Here in the question we are given a mixture of an insoluble solid and liquid . We are asked to separate it .In the process of filtration we separate an insoluble solid from a liquid by using a filter medium which allows the liquid component to pass but not the solid component. There are three types of filtration, they are biological ,chemical and mechanical filtration . The liquid component which passes through the filter is known as filtrate. The kidney is a good example of a biological filter. Activated carbon is a good example of chemical filtration. The removal of solid material from water using a filter is a very good example of mechanical filtration.
So from the above explanation and discussion it is clear to us hat

The correct answer of the given question is option: B. filtration

Note:
Always remember that a mixture of insoluble solid and liquid can be separated only using the process of filtration. The insoluble solid which cannot pass through the filter is known as residue and the liquid which is able to pass through the filter is known as filtrate.
