Distillation
Match the following.
(A) Simple distillation(1) To separate the liquids which are steam volatile, insoluble in water and contain non-volatile impurities.
(B) Fractional distillation(2) To separate liquids which decompose at a temperature below their normal boiling points.

Distillation
Name the metal which can be purified by distillation process.

Chemistry
Distillation
Assertion : Distillation is good for separating a liquid from a solution.
Reason : Distillation method works because the water evaporates from the solution, but is then cooled and condensed into a separate container.
