| Abstract: On account of the ease of polymerization of silicic acid, it is difficult to make an accurate determination of dissociation constant of monosilicic acid. So the values obtained by different investigators usually do not agree. By use of trimethylsilylation process, standard dissociation constant of monosilicic acid has been determined. And by ion strength extrapolation, thermodynamic dissociation constant has also been determined. These constants are in good agreement with the accepted values. |
