During a filtration experiment, a student uses filter paper to separate a precipitate. Which technique ensures faster filtration?
Correct answer: B. Folding the filter paper into a fluted shape
- A. Using a larger beaker
- B. Folding the filter paper into a fluted shape
- C. Heating the mixture
- D. Adding more solvent
Explanation
Fluted filter paper increases surface area, allowing faster. filtration compared to flat folding. Other options do not directly improve filtration speed.

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.
