Separation of Mixtures
- Different mixtures require specific methods of separation based on their physical and chemical properties.
- Some common methods of separation include:
- Simple Distillation: Used for separating liquids with significantly different boiling points.
- Fractional Distillation: Used for separating mixtures of liquids with closer boiling points.
- Distillation Under Reduced Pressure: Used for separating heat-sensitive liquids that may decompose at high temperatures.
- Steam Distillation: Used for separating substances that are volatile in steam from non-volatile impurities.
EXPLANATION:
- A. CHCl₃ + C₆H₅NH₂: These are heat-sensitive liquids. Therefore, Distillation under reduced pressure is used.
- B. Crude oil in petroleum industry: Crude oil is a complex mixture of hydrocarbons that have close boiling points. Therefore, Fractional Distillation is used.
- C. Glycerol from spent-lye: Glycerol is separated using Simple Distillation.
- D. Aniline-water: Aniline and water are separated using Steam Distillation as aniline is volatile in steam.
- A - I (Distillation under reduced pressure)
- B - III (Fractional Distillation)
- C - IV (Simple Distillation)
- D - II (Steam Distillation)
Therefore, the correct answer is A-I, B-III, C-IV, D-II.
