Webb6 maj 2014 · The results showed that the form of the carbon source in the electrolyte, such as HCO 3-, CO 32- and H 2 CO 3, had a strong effect on this reaction, which was controlled by the pH of the electrolyte. Furthermore, high concentration of the HCO 3- and elevated temperature can strongly improve the reaction current density. Keywords Webbas a function of pH. In soil systems where there may be an external (to the carbonate system) control on pH it would be handy to know the distribution of the carbonate species given pH. This distribution of carbonate species can be derived from the Henderson-Hasslebach relationship knowing pH and pK’s. A slightly different approach is shown next.
