Abstract
The adsorption of stabilising ion H+ has been determined for a precipitate of hydrous ferric oxide and that of SO4″ for the positively charged sol of hydrous ferric oxide during its coagulation as affected by potassium sulphate in presence of various non-electrolytes. The adsorption of both the stabilising and coagulating ions decreases in presence of ethyl alcohol and acetone, an increase is, however, observed in presence of glucose and urea. With gelatin at lower concentration the adsorption of both H+ and SO4″ decreases whilst the reverse is noticed at higher concentrations. It is concluded that the cutting down of the adsorption of either the stabilising or the coagulating ion cannot explain sensitisation or stabilisation.
