What happens when a substance dissolves in the watery solution outside of a cell and equilibrium is disrupted?
Osmosis is the diffusion of water down a concentration gradient through a partially permeable membrane. In the case of cells, its the cell membrane that the water will go through. Particles tend to diffuse down a concentration gradient to create a chemical equilibrium between the two sides.
When one side is disrupted, the system itself will counteract that change to shift towards the equilibrium. In chemical reactions, this is known as Le Chatelier's principle.
