Diffusion coefficient of liquids and aqueous solutions (table of values)
The solution diffuses into pure water.The valuesof the diffusion coefficientsare expressed in cm2/day. Concentration of electrolytes in gram equivalents per liter of solution, for the non-electrolytes - in moles. The temperature t ° C is listed in the table.
