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. WebbTherefore, Sodium carbonate is a basic salt that is formed by the neutralization of a weak hydrochloric acid by a strong base Sodiium hydroxide.
