Diffusion

In solutions or gases, particles (whether atoms, molecules, or ions) normally tend to move in a random order. Differences in concentration, however, can change that randomness.

Diffusion is the net movement of particles from a highly concentrated region across a concentration gradient to a region of lower concentration, resulting in equilibrium.

Concentration Gradient

A concentration gradient is a change in the concentration level of a substance from an area of high concentrationto an area of lower concentration.

Top

Equilibrium

In a solution containing areas of high concentration and other areas of lower concentration, particles will move in a semi-random order until the entire solution has the same concentration throughout. At this point equilibrium is achieved.
