Figure 3. Histogram representing the concentrations of the five groups of chemical species present in a solution 0.01 M Zn2+ + 0.01 M EDTA4- + 0.25 M NH3 + 0.25 M NH4+ + 10-6 M Eriochrome Black T (the same solution presented in Figure 1). The log of the concentration of a selected group of chemical species can be read in correspondence of the apex of each bar
