Question

How does the particle size vary in a true solution a suspension and a colloid?

Answer 1

A true solution is a homogeneous mixture of two, as well as the mixture of more than two substances.

Even a colloid is a homogenous-looking at the same time heterogenous mixture.

Of course suspension is a heterogenous mixture of a solid dispersed in a gas or liquid.

Overall, solute can't be seen with a microscope.

Answer 2

In a suspension the size of the particles is of the order 10^-5 or larger.

The most characteristics property of colloid particle is its size ranging from 10^-7 to 10^-5 cm.
