Experimental mutual diffusion coefficients of potassium chloride, magnesium nitrate, cobalt chloride and beryllium sulphate in aqueous solutions have been compared with those estimated by the Onsager-Fuoss. From the observed deviations, we are proposing a model that allows to estimate the percentages of H3O+ (aq) resulting of hydrolysis of some ions (i.e. beryllium, cobalt, potassium and magnesium ions), contributing in this way to a better knowledge of the structure of these systems.
