摘要: THE properties of silicic acid sols have been studied by several investigators1–10. Differences opinion1,2,3 expressed as to whether the possess any intrinsic character. In a number publications from this laboratory interactions with bases11,12,13,14, neutral salts15,16 and acids17,18 discussed. The even after purification prolonged electro-dialysis free acidities order 10–4 N. Their ultra-filtrates practically reaction showing that mobile H+ ions associated continued buffer action beyond first inflexion point takes place, second (Fig. 2) between PH 11·0 11·7 corresponding formation NaHSiO3 is observed13. An at pH 11·8 in titration curves sol concentrated alkali has observed Tread-well Konig4.
