a colloid contains larger particles than a solution. the particles are still too small to be seen easily, but are large enough to scatter a light beam

Use the Tyndall Effect shine a light through it. If the light is scattered then it is colloidal. Both colloids and suspensions are heterogeneous. A solution will not show the beam through it's substance but the colloid will. The particles in the suspension will eventually settle at the bottom, showing that it is NOT a solution.
One true way to identify a colloid solution is by observing the Tyndall effect, which occurs when light is scattered by the particles in the colloid. If you shine a beam of light through the solution and see a visible path of light, it indicates the presence of dispersed particles typical of a colloidal system. Additionally, colloids typically do not settle upon standing, distinguishing them from suspensions.
Solutions are mixtures on an atomic or molecular level; the mixture is so fine grained that you could never see it with a microscope. All you would see is a homogeneous substance. Colloidal suspensions contain tiny particles that you might be unable to see with the unaided eye, but which you could see with a microscope.
The traditional test is that a suspension scatters at least some of any light that passes through the suspension, while a solution does not.
A colloid is frequently opalescent and has more than one phase; the dimension of particles is in the range 1 nm-1μm.A true solution has only one phase and is clear.

Can you tell the difference between Vyvanse and Concerta in a drug test
An unsaturated solution can dissolve more solute at a given temperature, whereas a saturated solution contains the maximum amount of solute that can be dissolved in the solvent at that temperature. You can tell the difference by observing whether there is still undissolved solute present in the solution (unsaturated) or if the solution is clear with no solute visible (saturated).
