Kinetics and Mechanism of Hydrolysis of Hexacoordinate Fluorosilicates in the Presence of Ammonium

The hydrolysis kinetics of hexacoordinate silicon fluoro complexes - constituents of fluorosilicic acids - at various ammonium concentrations was studied in the temperature range 278.2-298.0 K. The observed reaction rate coefficients, catalysis coefficients KNH4+ , and activation parameters of hydrolysis involving NH4+ were calculated. A possible mechanism of the promoting influence of NH4+ was suggested, which implies that the weakening of Si-F bonds results from an electron-density shift towards the cation because of the formation of an ion associate with the silicon fluoro complex, which presumably incorporates water molecules.
