Abstract
ACCORDING to the stability theory of hydrophobic colloids of Derjaguin and Landau1 and Verwey and Overbeek2 (D.L.V.O. theory) the electrolyte concentration required to produce coagulation increases with the surface potential of the colloidal particles. However, for silver halide sols, the electrolyte concentration increases with surface potential for univalent flocculating ions, either decreases or remains approximately unchanged for divalent ions and decreases for tri valent ions3,4. This can be explained by incorporating into the D.L.V.O. theory the so-called discreteness-of-charge effect5–8.
