In a distillation to separate two liquids with boiling points of 80°C and 100°C, why are anti-bumping granules added?
Correct answer: B. To prevent superheating and ensure smooth boiling
- A. To increase the boiling point
- B. To prevent superheating and ensure smooth boiling
- C. To enhance the separation efficiency
- D. To reduce the distillation time
Explanation
Anti-bumping granules provide nucleation sites, preventing superheating and ensuring smooth boiling during distillation.

About Experimental Techniques in Chemistry
Separation methods are selected according to differences in solubility, particle size, volatility and sublimation behaviour. Filtration and crystallisation separate insoluble or dissolved solids, sublimation isolates suitable volatile solids, distillation separates liquids by boiling point, and solvent extraction transfers a substance between immiscible solvents.
