The electrogeneration of molybdate ion (MoO4-2) for possible use in a coulometric determination of thorium or lead has been investigated. Constant current electrolyses were used to study the oxidation of molybdenum to molybdate. It was found that molybdate can be generated in 1N HCl with from 96 to 100% efficiency. The current efficiency for molybdate generation in less acidic media could not be determined accurately. Coulometric titrations of known amounts of thorium with electrogenerated molybdate have been carried out. The endpoints, which were determined amperometrically, were found to be inexact and reproducible to only ± 5%. Coulometric titrations of lead with electrogenerated molybdate have produced sharp and clear endpoints.
