The self-diffusion coefficient of neat water is: 2.299Â·10â9 mÂ²Â·sâ1 at 25 Â°C and 1.261Â·10â9 mÂ²Â·sâ1 at 4 Â°C. Chemical diffusion occurs in a presence of concentration (or chemical potential) gradient and it results in net transport of mass. This is the process described by the diffusion equation.
