Abstract
An incomplete reduction of molybdate ions in solutions of pH 3.0–9.0 is shown to be accelerated by ammonium ions: a film of hydrated oxides of molybdenum in lower oxidation states forms on the cathode in their presence. Products of the incomplete reduction adsorbed at the cathode block its working surface.
