Summary A colloidal solution of cobalt tungstate of negative charge and highly lyophilic character was prepared by mixing sodium tungstate and cobalt chloride solutions in presence of glycerine and caustic soda. The sol exhibits protective action against the electrolytic coagulation of hydrophobic sols of opposite electrical character. In its coagulation both the anions and cations follow theHofmeister series. The sol is highly viscous and exhibits the acclimatisation effect and also the ionic antagonism. 相似文献
