Проведено сравнение экспериментальных коэффициентов взаимной диффузии хлористого калия, нитрата магния, хлорида кобальта и сульфата бериллия в водных растворах с данными, полученными методом Онзагера-Фуосса. Исходя из наблюдаемых отклонений, нами предложена модель, которая позволяет оценить процентное содержание H 3O + в результате гидролиза некоторых ионов (т.е., бериллия, кобальта, калия и магния), способствующая, таким образом, к лучшему пониманию структуры этих систем. Диффузия сульфата бериллия, несомненно, наиболее активно проходит при гидролизе ионами бериллия.

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 H 3O + (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. The diffusion of beryllium sulphate is clearly the most affected by the beryllium ion hydrolysis.
