Question

Colloidal state is homogeneous in nature.
A. True
B. False

Answer 1

Hint: Colloidal solutions consist of three essential components which are dispersed phase, a dispersed medium and a stabilising agent.A colloid is actually a heterogeneous mixture in which the dispersed particles are intermediate in size b/w those of a solution and a suspension. As the dispersed particles of a colloid are not as big as those of a suspension, they generally do not settle out upon standing.

Complete answer:
A colloidal solution, generally identified as a colloidal suspension, which is a mixture in which the substances are usually suspended in a fluid. A colloid is a very tiny small material that is often spread out all via another substance. These are actually heterogeneous in nature however seems to be homogeneous. These solutions can form Tyndall effect and are actually very stable in Nature.

Colloidal solutions usually consisting of the following three essential components:
(i) A Dispersed phase: It is also called a discontinuous or inner phase. It consists of very discrete particles mostly larger than ordinary molecules and however in this small particles of solute is usually diffused in solvent.
(ii) A Dispersion medium: It is that medium in which the dispersed phase is present. It consists of continuously interlocked molecules.
(iii) A Stabilising agent: This is a substance which used to keep the colloidal particles apart from each other. Some of the colloids are self-stabilizers.
Colloids appear to be homogenous because the particles of a colloid are quite uniformly spread throughout the whole solution. Because of the relatively smaller size of particles, as compared to that of a suspension, the mixture looks homogeneous. Due to the smaller size of colloidal particles, it is difficult to see them with naked eyes.
Hence, Colloidal substances are not homogenous in nature.

So, option B is correct.

Note: Colloidal substances look homogenous but they are heterogeneous in nature. A colloid is a very tiny small material that is often spread out all through another substance. Some of the examples of colloids are fog, smog, sprays, milk, etc.
