Testing the Cell for Measurement of Diffusivity in Liquids

Popis výsledku v původním jazyce

For the measurement of diffusion coefficients in liquids a method has been suggested where the time dependence of the component concentration in a small volume of the solvent, which is in the contact with the solution inside the vertical bundle of capillaries plugged at the lower end, is monitored. This method has been tested using sulfuric acid, which diffusivity is published. It has been found that the calculated values of acid concentration are in good agreement with those obtained experimentally. The calculated values have been obtained by a numerical solution of Fick?s second law, the concentration dependence of diffusivity of sulfuric acid in the capillaries being considered.
