Why do the components of a colloid not separate?

Answer 1

Most colloidal suspensions have a size small enough not to be affected by gravity and the thermal forces give their motion. In the case of charged colloids, a diffuse layer is forming around the particles, composed mostly by counter-ions (small ions of opposite sign). These counter-ions are subject to attraction toward the surface by the opposite charge and are depleted from the surface by the thermal forces. When two charged colloidal particles approach each other, a repulsive force results, due to the overlap of these diffuse layers. This repulsive force does not allow for the particles to get in contact and aggregate. Without addition of salt or oppositely charged polymers, a colloidal suspension which is not affected by gravity can stay stable indefinitely.

Answer 2

A colloid is not a true solution because the size of solute particles in colloidal solution are larger than the size of solute particles in True solutions. And unlike True solution colloid scatter beam of light and renders its path visible.

Answer 3

The particles in a colloid are small and evenly dispersed throughout the mixture, preventing them from settling out due to gravity. Additionally, the continuous movement of the particles due to Brownian motion helps to keep them suspended and evenly distributed in the solution. Additionally, the surface charge on the particles may provide repulsion forces that prevent them from aggregating and settling.

Answer 4

Because the particles are so small and don't settle out at the bottom
