Abstract: The adsorption of peptising and coagulating ions play an important role in defining the stability of a sol. We have investigated here the extent to which the stability of the sols of hydrous ferric oxide is affected by a change in the dielectric constant of the dispersing medium for H^+ and SO_4^2- as stabilising and precipitating ions. It has been concluded that it is not possible to explain the sensitisation or stabilisation of a sol on the views advanced by Weiser, as the adsorption of either of the ions is found to vary according to the dielectric constant values of the dispersing medium.
