Abstract
The first determination of the coefficient of diffusion of an electrolyte in a gel appears to have been made by Öholm (8) who calculated the coefficient of diffusion of potassium chloride in gels of gelatin of various concentrations, from the results of the chemical analysis of four successive layers of a cylinder of the gel, into which diffusion of the salt from a normal solution had proceeded. A part from these determinations of Öholm the only measurements of the coefficients of diffusion in gels are those made by Stiles and Adair (1, 9, 10 and 11) by means of the indicator method.Keywords
