Question

The size of the colloid particles is :

• A. $<$ suspension particles
• B. $>$ suspensions particles
• C. $>$ true solution particles
• D. none of the above

Answer 1

Answer: (A), (C)

The size of the colloid particle (1 nanometer - 1 micrometre) is less than the suspension particles (1 nm- 1000 nm).

The size of the colloid particles is greater than the true solution particles because particles in true solutions are very small and they can move freely.

Hence, option $B$ and $C$ is correct.
