In order to avoid the dilution of the sol on the addition of an electrolyte solution to a definite volume of the sol (ferric hydroxide sol A and the arsenious sulphide sol) weighed amounts of different solid electrolytes were added the mixture was centrifuged and the pH of the supernatant liquid determined either by the colorimetric or by the e.m.f. [...] Assuming an equilibrium between the ions on the surface with hydrogen ions in the solution it would be evident that the stablity of higher valent ions which corresponds to higher stages of the dissociation of the base requires a pa value lower than that for the lower valent ions. [...] Lastly the process of coagulation may affect the pH by the entrainment of ions or by liberation of a part of the surface ions. [...] The difference in the effects of KNO3 and NaNO3 on the pH and in the liberation of the chlorine has some points of similarity. [...] The reaction that takes place is thus complicated and theoretically one can conceive the following reactions being responsible for the ultimate result : (a) the reaction of the primarily or electrically adsorbed ion and those in the mobile layer with those in solution ; (b) the tranformation of SO4" or C204" ions to HSO4' or HC204' in the intermcellary liquid itself and (c) the entrainment
