On the existence of peroxocarbonates in aqueous solution
Abstract
The presence of a peroxocarbonate species, likely to be HCO4– in pH-dependent equilibrium with CO42–, in solutions of HCO3– in an excess of H2O2 is inferred from Raman and 13C n.m.r. spectroscopy; similar evidence is presented for the presence of CO42– in solutions prepared by dissolving solid peroxocarbonates (NaHCO4·H2O and K2C2O6) in aqueous alkali.
