Theoretical reaction pathways for the formation of (Si(OH)5)(1-) and the deprotonation of orthosilicic acid in basic solutionThe stability of (Si(OH)5)(1-) is predicted by means of molecular orbital calculations. Si is predicted to be as stable in basic aqueous solutions as hydrated (/OH/3SiO)(1-) and more stable than Si(OH)4 + (OH)(1-). Vibrational analysis of (Si(OH)5)(1-) predicts Raman and IR spectra that are not compatible with the presence of Si in some silicate glasses under ambient temperature compression.
