Question
Which characteristic is true with respect to colloids?
Answer: Option A
:
A
Acolloidis a heterogeneous mixture in which the particles of the dispersed phase are distributed non-uniformly in the dispersion medium.
A colloidal solution is always made up of two phases- dispersion medium and dispersed phase. The two phases of a colloid can be a solid, a liquid or a gas. However, its constituent particles are very small in size. Hence, it cannot be separated by filtration.
Examples of colloids are blood, paint, etc.
