Question

The method of separating mixtures based on differences in volatility of components in a boiling liquid mixture is known as:

• A. Evaporation
• B. Distillation
• C. Leaching
• D. Fractional separation

Hint:

Distillation is the backbone of the alcohol industry and is used in food processing to recover aromatic essences and deodorize edible oils.

Answer 1

The Correct Option is B

When a boiling mixture contains two or more liquids, the more volatile one evaporates faster and can be collected separately by condensing its vapour, while the less volatile part stays behind as residue. This separation, based purely on differences in how easily each component vaporises, is called distillation. Evaporation, in comparison, usually removes a volatile solvent like water to concentrate a non-volatile solid, not to separate two liquids from each other.
