Research the Quantitation of Buffering Action. Ii. Applications of the Formal and General Approach. Buffering in Pure Water

Buffering of H+ and OHions in pure water probably represent the most primal physicochemical buffering phenomena, and their quantitative description is of great interest. In this context, “pure water” shall mean water without any solutes that could act as H+ buffers. In the following, it is understood that addition of H+ ions to pure water, or removal of H+ ions from it is carried out in the form of “strong” acids or bases, respectively. To obtain an explicit quantitative description of buffering in pure water according to our concept of buffering (Buffering I), we first recapitulate a standard mathematical model describing the concentrations of OHand H+ ions in water as functions of added strong acid or base. Then, we form the corresponding “buffered system” and derive from it the four buffering parameters t, b, T, and B. Quantitative description of [OH] and [H] concentrations in pure water with added strong acid or base
