Abstract

The coagulation values of potassium perchlorate, potassium chlorate and sodium benzoate on positive silver bromide sol, and of potassium sulfate on positive sols of silver chloride, silver bromide and silver iodide in statu nascendi for various concentrations of the stabilizing ions have been determined . The experimental results were used for the discussion of the dependence of the coagulation values on the charge of the sol, the solubility of the compound formed between the stabilizing and the counter ion, the valency of the counter ion and the density of the charge at the surface of sol particles.
