WebApr 28, 2024 · Osmotic pressure can be thought of as the pressure that would be required to stop water from diffusing through a barrier by osmosis. In other words, it refers to how hard the water would “push” to get through the barrier in order to diffuse to the other side. Osmotic pressure is determined by solute concentration – water will “try ...
