Abstract Crossover 13 C NMR experiments between 13 Ccarbonate and 18 Ocarbonate in aqueous solution confirm the combined action of two oxygen‐exchange modes. The isotopomeric carbon dioxides formed in the hydrolysis equilibrium of the labeled carbonate anions react with hydroxide with formation of hydrogencarbonate and with isotopomeric carbonate anions yielding the corresponding dicarbonate species, which, in the back reaction, form carbon dioxide and carbonate anions with distributed oxygen.
