The net movement of small, uncharged atoms and molecules through the plasma membrane will end when the concentration of a solute is equal on both sides of the membrane. This is because at equilibrium, the concentration gradient that drives diffusion is eliminated, resulting in no net movement of molecules across the membrane.
