摘要:
Oxygen formed electrolytically from hydrogen peroxide at the surface of the dropping mercury electrode was determined and the charge needed for its electrolysis measured. The yield is about 50% of the theory, which indicates oxide formation. This is supported by formation of black precipitate on dropped off mercury. Reduction of oxygen in alkaline media is thus not a simple reversible process, but complicated by mercury oxide formation, similarly as on solid electrodes.
