Abstract
WE have investigated the conductivity of very dilute (N/200–N/500) solutions of sodium normal silicate during neutralization by hydrochloric acid, and the neutralization of freshly formed silicic acid by caustic soda, at 15° C. and 100° C. Hagg found in approximately N/10 solutions inflexions in the pH curves corresponding to Na2O.SiO2 and Na2O.2SiO2 approximately.
