E_{pc_x} = cathodic peak potential, E_{pc_y} = anodic peak potential, and E^o′ = standard reduction potential.

Rows containing nonbold values are original data (V vs Ag/AgCl) and rows containing bold values are V vs standard hydrogen electrode (SHE).

For calculation, V vs SHE = V vs Ag/AgCl + 0.210 V.⁴⁵

E^o′ was calculated only at pHs 3.5 and 4.0 because these had |I_pa₄/I_pc₃| ≈ 1.0 (see Table S1) for data.
