Question

The process of adding chemical substance to help the suspended solid particles settles down faster is known as

• A. sedimentation
• B. decantation
• C. filtration
• D. loading

Answer 1

Answer: (A), (D)

loading

1. Loading is a process in which we add an external substance to the mixture which helps in quick settling down of the sediment.
2. Process of setting down of the insoluble solid particles in a solid -liquid solution is known as sedimentation.
3. Filtration is a process in which we separate solid particles from a mixture of solid-liquid with the help of filter paper .The solid particles settles on the filter paper as residue whereas the liquid particles passes as filtrate.
4. Decantation is a process in which in which the heavier particles settles down as sediment and the clear liquid is separated in the other beaker.
5. Therefore the correct answer will be option d.
