Abstract
The purpose of this investigation was to determine the time of set and the hydrogen ion concentration of a silicic acid gel, basic in nature. A gel prepared from a mixture of 1.2511 normal sodium silicate solution and 1.0158 normal ammonium chloride was used for this purpose. The possibility of measuring the hydrogen ion concentration by the indicator method was used with considerable success by Prasad and Halliangadi (1). Previous work on this problem at Union by Marotta (2) pointed out the uncertainty of the glass electrode method due to the effect of the silicate on the electrode. The possibility of measuring the hydrogen ion concentration with the quinhydrone electrode was studied in this laboratory.
