WebJan 22, 2024 · By definition, osmosis is the movement of any solvent through a selectively permeable membrane into an area of higher solute concentration, the result of which will be an equalizing of solute concentration on either side of the membrane. WebSolutes move by diffusion from regions of high concentration to regions of low concentration. Fick’s First Law of Diffusion states that the flux is proportional to the negative of the gradient of C: where Js is the solute flux, D is the diffusion coefficient, and ∂C /∂ x is the one-dimensional gradient.
