Question

The principle of filtration is that substances with particle size larger than the pore size of filter paper are retained on the filter paper and the rest of the fluid passes through it. True or false?

• A. True
• B. False

Answer 1

The correct option is A True

Filtration is used to separate the insoluble impurities from the solution. It uses the principle of size difference. Particles with size larger than the pores of filter paper are retained as residue on the filter paper and the rest of the fluid passes through it.
For example, clear water can be obtained from muddy water. As the mud has particle size larger than the pore size of filter paper, it is retained as residue and only clear water passes through it.
