The conditional potentials of redox systems not involving protons have been studied as a function of phosphoric acid concentration (1-14M), with the ferricinium/ferrocene couple as the comparison system. The following systems were considered: Cu(II)/Cu, Cd(II)/Cd, Sn(II)/Sn, Zn(II)/Zn, Ag(I)/Ag, Pb(II)/Pb, Hg(II)/Hg, Bi(III)/Bi and particularly Fe(III)/Fe(II) and Fe(II)/Fe. The hexacyanoferrate(III)/hexacyanoferrate(II) and iodine/iodide couples were also studied. The results are presented as a potential-H(3)PO(4) concentration diagram (or potential-acidity level diagram).
