| colloid |
Very finely divided solid particles that remain suspended in a solution; the removal of colloidal particles usually requires coagulation.

Colloidal particles are so small and light that they do not settle in water. The movement of water molecules is enough to keep them in suspension. It is important to remember that colloidal particles occur in a suspension, not a solution. A simple way to tell the difference is to shine a beam of light through the liquid. If you can see the beam it is a suspension.

| colloid |
a substance made up of a system of particles with linear dimensions in the range of about 10 -7 to 5 X 10 -5 centimeters, dispersed in a continuous gaseous, liquid, or solid medium whose properties depend on the large specific surface area. Particles in a colloidal system remain dispersed indefinitely.

| colloid |
Particles suspended in a liquid, which are larger than molecular size but small enough to be moved about by molecular collisions. These particles do not settle under gravity. Their surface area is very large per gram, and the particles have a charge due to ions sorbed on the surface. This charge prevents coagulation or clumping of the particles and therefore, coagulation can be brought about by neutralizing the charge.
