Al~traet--Two main views are found in the literature regarding the type of oxide formed on copper anodes in alkaline solutions. The one considers that copper oxidizes to Cu~O and CuO (or Cu(OH),) before oxygen evolution. Mftller is, however, of the opinion that a still higher oxide, Cu~O,, forms. Th
Galvanostatic cyclic anodic and cathodic polarization curves of seven copper-tin alloys were traced on O-01, O-1 and 2N NaOH solutions at 25". The tin content of the alloys was varied between 8 and 76 wt-%. The results obtained are explained in relation to the phase diagram of the copper-tin system.
Tin-amalgams of varying concentrations were oxidized galvanostatically in O-01,0-10 and 2~00 N NaOH solutions at 25Β°C. For each amalgam and solution composition a number of constant polarizing currents were used and cyclization was repeated until the oxidation (reduction) features of the amalgam bec
