Question

The method used to separate the volatile component(solvent) from its non-volatile solute is called:
A.Filtration
B.Evaporation
C.Condensation
D.Sublimation

Answer 1

Hint: volatility is a material quality which describes how readily a substance vaporizes. At a given temperature and pressure, a substance with high volatility is more likely to exist as a vapour, while a substance with low volatility is more likely to be a liquid or solid.
Complete step by step answer:
Volatility explains the tendency of a vapour to condense into a liquid or solid that is, less volatile substances will more readily condense from a vapour than highly volatile ones.
Evaporation is a technique which is used to separate the homogenous mixtures where there are one or more dissolved solids. This method dispels the liquid components from the solid components. The process involves heating the mixture until no more liquid remains. Before using this method, the mixture should only contain one liquid component, unless it’s not important to isolate the liquid components. This is because all liquid components will evaporate later on. This method is appropriate to separate a soluble solid from a liquid.
Hence, the volatile component (solvent) can be separated from its non-volatile solute by the method of evaporation. The volatile component evaporates leaving behind the non-volatile component.
Therefore, the correct answer is Option B.

Note: Filtration is a separation method which is used to separate out pure substances in mixtures composed of particles some of which are large enough in size to be captured with a porous material. Condensation is a process in which water vapour becomes liquid.Sublimation is a process in which a solid transforms into a gas phase without first melting to form a liquid phase.
