THE DEGREES OF ANION CONDENSATION IN SILICIC ACIDS AND SILICATES
THE SILICATE IS TRANSFERRED BY TREATMENT WITH METHANOLIC HYDROCHLORIC ACID INTO THE FREE SILICIC ACID CORRESPONDING TO THE ANION WHICH IT CONTAINS. IN FAVORABLE CASES, THE DEGREE OF CONDENSATION OF THE DISSOLVED SILICIC ACID CAN BE DETERMINED BY A KINETIC METHOD BASED ON THE RATE OF FORMATION OF THE MOLYBDATOSILICIC ACID COMPLES. WHERE A COMPLEX DISTRIBUTION OF ANION SIZES EXISTS, E.G., IN CALCIUM SILICATE HYDRATE GELS, THE METHOD DOES NOT GIVE ABSOLUTE RESULTS, THOUGH IT CAN BE USED TO FOLLOW CHANGES IN THIS DISTRIBUTION. /AUTHOR/
