The constituents of a mixture of and is separated by:
The constituents of a mixture of and is separated by:
The correct option is C Dissolving in water, filtration, and evaporation
The explanation for the correct option:
Different separation techniques are present depending on the property of the substances to be separated
(C) Dissolving in water, filtration and evaporation: To separate (calcium carbonate) and (sodium chloride) we can first put the mixture in water, where sodium chloride will dissolve in water and calcium carbonate remain as undissolved.
The undissolved calcium carbonate can be then separated by using filter paper, where it will not pass through the filter paper, remain above the paper and dried by pressing filter paper.
The dissolved sodium chloride then separated by evaporating the water (solvent) part
The explanattion for the incorrect option:
(A) Using evaporation method: It used to separate dissolved solid from the solution by heating the mixture allowing to evaporate the liquid part leaving behind the solid particles.
Salt from salt solution can be separated by this process.
(B) Using the sublimation method: Mixture of sublimable and nonsublimable substance can be separated by this technique.Mixture is take in a chia dish covered with an inverted funnel and heated (stem of the funnel covered with a cotton to prevent the escape of the vapours).
Th sublimable substance which undergo state change from solid state to gaseous state rises, and on the cooler sides of the funnel it get solidified and nonsublimable substance remian within the china dish.
Example: mixture of ammonium chloride and sand can be separated using sublimation, since ammonium chloride is a sublimable substance.
(D) Using the distillation method: The mixture of miscible liquids can be separated using distillation, if the boiling point difference greater than .The mixture is heated in a distillation flask and component with lower boiling point vaporise and condense then collected in the receiver.
Therefore, option (C) is correct. i.e.., and can be separated by dissolving in water, filtration and then evaporation methods.
