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. WebbpH is defined as the negative of the base-ten logarithm of the molar concentration of hydrogen ions present in the solution. The unit for the concentration of hydrogen ions is moles per liter. To determine pH, you can use this pH to H⁺ formula: pH = -log([H⁺]) Step by Step Solution to find pH of 0.12 M : Given that, H+ = 0.12 M
