Abstract
Concentrated KOH + K2Zn(OH)4 + H2O and KOH + H2O electrolytes were inv estigated by cyclic voltammetry and hydrogen-electrode rest potential measurements. The adsorption of zincate ions on the platinum electrode is demonstrated by modifications of the voltammograms and shifts in r est potentials. Interference with the hydrogen reactions in the voltam mograms by zincate ions prevents the use of the H-2/Pt reference elect rode for rest potential measurements in zincate-containing solutions.
