The shift in the potential of the zinc stripping current maximum observed in anodic stripping voltammetry is related to the free energy of the reaction between ionic zinc and a complexing anion. The model was tested using the zinc hydroxyl system; the agreement with experimental results was excellent. The findings suggest the existence of the aqueous complex, Zn(OH) 2 o , which has been reported only once before. The stability constant calculated here is in good agreement with the single published value.
