Three students Ankit, Dinesh and Manoj were given three unknown substances X, Y and Z respectively during the lab activity.

On the basis of these properties, which student has chosen the correct separation technique, to separate a substance from the substance-water mixture?

Options

A. Ankit - Separating funnel
B. Dinesh - Distillation
C. Manoj - Fractional distillation
D. All are correct.

Answer

C

Explanation

Ankit has substance .X. which is soluble in water so, it cannot be separated from water by using separating funnel. .X. can be separated from the mixture by using distillation method as there is sufficient difference in the boiling points of .X. and water (`100 - 56 = 44^@ C`). Dinesh has substance .Y which is insoluble in water so, it can be easily separated by using separating funnel. Manoj has substance .Z. which is soluble in water and has boiling point very close to water so, it can be separated by using fractional distillation method.
