STUDIES IN THE NEGATIVELY CHARGED COLLOIDAL SOLUTIONS OF VARIOUS FERRIC SALTS. PART IV. NEGATIVELY CHARGED FERRIC TUNGSTATE SOL

Negatively charged ferric tungstate sole have been prepared by dispersing freshly precipitated ferric tungstate by caustic soda, in presence of glucose or glycerine. The empirical formula of the sol. peptised in presence of glucose is 13Fe₂.O₃.Fe₂(WO₄)₃  H₂O and that of the sol peptised in presence of glycerine is 17Fe₂O₃, Fe₂ (WO₄)₃. 15H₂O Various other characteristics of the sole have also been investigated
