Self diffusion, exemplified with an isotopic tracer of radioactive isotope 22 Na Example of chemical (classical, Fick's, or Fickian) diffusion of sodium chloride in water. Fundamentally, two types of diffusion are distinguished: Tracer diffusion and Self-diffusion, which is a spontaneous mixing of molecules taking place in the absence of ...
Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move from a region of high concentration to a region of low ...
Diffusion is a property of substances in water; substances in water tend to move from an area of high concentration to an area of low concentration. [26] Blood flows by one side of a semi-permeable membrane, and a dialysate, or special dialysis fluid, flows by the opposite side.

The higher the diffusivity (of one substance with respect to another), the faster they diffuse into each other. Typically, a compound's diffusion coefficient is ~10,000× as great in air as in water. Carbon dioxide in air has a diffusion coefficient of 16 mm 2 /s, and in water its diffusion coefficient is 0.0016 mm 2 /s. [1] [2]

The diffusion process proper takes place on the 10-16% of sugar containing cells that have not been opened. First hot water is applied to kill the protoplasm of the cells. This makes that the walls of the cell becomes semipermeable. By osmosis, water or thinner juice can then enter the cell and replace heavier juice until an equilibrium is reached.
