...the phenomena of diffusion, A. Fick1 put forward, tentatively, the statement that, the quantity of a salt which diffuses through a given area is proportional to the difference between the concentrations of two areas infinitely near one another. This fundamental supposition made by Fick follows, as a necessary... | |

...thoroughly investigate this matter, and in 1855 Fick advanced the theory that, " the quantity of a salt which diffuses through a given area is proportional to the difference between the concentrations of two areas infinitely near one another." The truth of this statement was demonstrated by an investigation... | |

...wanders in a solvent, is proportional to the degree of concentration.l' Therefore, "the quantity of a salt which diffuses through a given area is proportional to the difference between the concentrations of two areas infinitely near one another."" In other words, diffusion is proportional to the difference... | |

...diffusion. The first of these conclusions was expressed by A. Fick in the following form: The quantity of a salt which diffuses through a given area is proportional to the difference between the concentrations of two areas infinitely near one another. This law is known as Fick 's law of diffusion, and has been... | |
