Question
Why is filtration a better technique than sedimentation and decantation ?
✓

Answer

Filtration is a better technique than sedimentation and decantation because it can separate very fine insoluble particles as compared to the latter. Besides the filtrate obtained is generally pure solvent. In decantation when we pour out supernatant liquid there are chances of their getting mixed up with solute particles.
