Dependence of the diffusion rate on the viscosity of the medium.

Diffusion is the mixing ability of chemicals. What will be the relationship between this ability, its speed and the viscosity of the medium. It would be logical to assume that the thicker the substance, the denser it is, the slower the mixing rate. Conversely, the less viscous the substance, the easier it is for the particles that make up the substance to undergo mixing. The diffusion rate also depends on the state of aggregation of the substance. In a gas, diffusion is the fastest, in a solid, respectively, the slowest.
