Question

Match the following mixtures with their appropriate separation techniques:

Mixtures	Separation Technique
(a) Benzene and Toluene	(i) Distillation
(b) Orange dye in water	(ii) Fractional Distillation
(c) Acetone and water	(iii) Evaporation

• A. a- iii; b- ii; c- i
• B. a- i; b- ii; c- iii
• C. a- ii; b- iii; c- i
• D. a- ii; b- i; c- iii

Answer 1

The correct option is C a- ii; b- iii; c- i

• The boiling point of benzene is ${80}^{o}C$ and that of toluene is ${110}^{o}C$. Since the difference in their boiling points is very less, it can be separated by fractional distillation.
• Ink is a mixture of dye and water, which can be separated by evaporation.
• The boiling point of acetone is ${56}^{o}C$, whereas that of water is ${100}^{o}C$. Since the difference in their boiling points is large, simple distillation is used to separate this mixture.
