How do the particles that are dispersed in a colloid differ from the particles suspended in a suspension?

The colloid particles are less dense.

The colloid particles are more solid.

The colloid particles are smaller.

The colloid particles are larger.

Answer: The correct option is that the colloid particles are smaller.

Explanation: There are 3 types of solutions:

1) True solutions: These are the solutions in which the size of the particles are less than 1nm. These are considered as homogeneous mixtures.

2) Colloids: These solutions are the solutions in which the size of the particles lie in the range of 100nm to 1nm. These are assumed to be homogeneous mixtures but actually are heterogeneous mixtures.

3) Suspension: These solutions are the solutions in which the size of the particles are greater than 100 nm. These are considered as homogeneous mixtures.

The particles which are dispersed in a colloid have smaller particles than the particles which are dispersed in a suspension.
