WebThe influence of temperature on the titration curve of casein may be accounted for by the Bjerrum theory of ionization of ampholytes. THE EFFECT OF TEMPERATURE ON … This equation for gives satisfactory agreement with experimental measurements for low electrolyte concentrations, typically less than 10 mol/L. Deviations from the theory occur at higher concentrations and with electrolytes that produce ions of higher charges, particularly unsymmetrical electrolytes. Essentially these deviations occur because the model is oversimplified, so there is little to be gai…
