The influence of F-, Cl-, Br-, and I- ions on the kinetics of dissolution of (100) and (111) faces of a copper single crystal in a sodium hydroxide solution in the presence of oxygen was investigated. The results are interpreted in terms of adsorbability of the anions. Differences between the crystal faces are attributed both to the potentials of zero charge and to the different kinetic behaviour of these faces in pure sodium hydroxide solutions.
