The equation for an acid is just HA = H+ + A- … Webb29 jan. 2015 · The pH of the solution is #"10.5"#, which means that the dominant species form of the acid will be #HA^(2-)#. This happens because #"pKa"_1 < "pH" < "pKa"_2#. Now you have to set up a system of three equations with three unknowns - the concentrations of the acid forms. From now on, I'll use this notation for simplicity
