ZINC DISSOLUTION IN LECLANCHE ELECTROLYTE
1975
The rate and morphology of zinc dissolution were studied in a Leclanche electrolyte of composition 0.5 mol dm-3 ZnCl2 and 5 mol dm-3 NH4Cl. A gelled electrolyte layer 2 x 10-3 m thick on the zinc surface was found to reduce the corrosion rate by an order of magnitude and to promote even dissolution. The corrosion results are interpreted in terms of a diffusion-controlled cathodic reaction involving O2 dissolution and metallic impurity deposition.
