Chapter 5, Problem 19STP

Interpretation Introduction

Interpretation: The method of separating the components of the mixture depends on different boiling points of the components of a mixture needs to be explained.

Concept Introduction: There are various types of separation techniques used for segregating or separating the mixture of substances that are done to remove the unwanted materials. Some common methods of separating the mixtures are handpicking, winnowing, distillation, and threshing, sieving, evaporation, separating funnel, filtration or sedimentation, magnetic separation, etc.

Answer to Problem 19STP

The correct option is D.

Explanation of Solution

Mixtures can be separated by using a variety of techniques i.e. chromatography method involves the separation of solvent on a solid medium, distillation on the basis of differences in the boiling points, evaporation methods remove a liquid from the solution by leaving behind the solid material and filtration method separates the solids of different sizes.

Hence, the correct option is D.

Conclusion

Distillation method used for separating the mixture on the basis of differences in the boiling points. Hence, the correct option is D.
