Abstract
THE chemistry of silicic acid in solution is rather ill-defined1 owing to the extremely weak nature of this acid2 and its tendency to polymerize3,4. As there are many instances where hydrogen peroxide effectively prevents anionic polymerization5,6, an attempt was made to investigate the hydrolysis of silicate ions in the presence of hydrogen peroxide by means of accurate conductivity7, and pH measurements. For comparison, the same technique was applied to an identical series of solutions in the absence of hydrogen peroxide. Fig. 1 shows the results of the investigation on solutions which were 0.01 M in sodium silicate and, in the case of the ‘peroxidized’ system, approximately 0.1 M in hydrogen peroxide; sulphuric acid was 0.498 M.
