Technical Notes Gallium Oxidation in Alkaline Solution

The electrochemistry of gall ium is important not only in practical applications, but also for theoretical considerations due to its existence as either a liquid or a solid in aqueous electrode systems. Past studies of the anodic oxidation of Ga in alka-line solutions have been limited. It is the purpose of this study to investigate in somewhat more detail, using cyclic voltammetry, the first stages of anodic oxidation of Ga in aqueous NaOH solutions. Experimental A three compartment Pyrex cell was used. Carbonate free NaOH solutions were made of re-agent grade materials. Solutions were made from water doubly distilled from a basic permanganate solution. The reference, counter, and test electrodes were eac
