Which of the following apparatus is not used while filtering out the chalk powder from water?
The correct option is D Sieve
The explanation for the correct option-
(D) Sieve
Sieve - It is a utensil or vessel that has many holes of the same size or it is made of a mesh of wires and allows only particles to pass through that are smaller than the holes of the sieve. It is used in the process of sieving.
The explanation for the incorrect options-
(A) Funnel - it is an apparatus used to transfer solutions from one vessel to another.
(B) Beaker - it is used to keep and prepare solutions.
(C) Filter paper - it is a special type of paper that is used to separate insoluble impurities from a liquid.
All of the above apparatus is necessary for the process of filtration.
Hence, option (D) is correct. A sieve is not used while filtering out the chalk powder from water.
