The passivation of zinc electrodes in alkaline solution has been studied at various rates of solution flow. At constant cd the passivation time is increased by an increase Passivation-time/cd data can be correlated in the form in solution velocity. (i -i&l'\* = k, where i, and k arc umstants for giv

## Abstract The solubility of lead in zinc sulphate solutions was determined over the range of zinc concentration from 75 to 125 g./l., acid concentrations from OT to 75 g./l., and temperatures of 20°‐30° c. In this range of variables normally encountered in electrolytic zinc refineries the lead so
Passivation of spec-pure Sn was studied in aerated, unstirred solutions of acid sulphate (H2S04/Na2S04) and neutral suphate (Na2S04) using the potentiodynamic technique from an initial cathodic potential (-ve to open circuit potential) in the anodic direction and backwards to the initial potential.
## Al&met-Potentiodynamic experiments in the range 600-06 mV/s, designed to elucidate the processes by which the zinc electrode in alkali becomes passive, are described. At low overpotentials the dissolution process is a complex solution mechanism in which soluble zincate species leave the electro
