An oxidimetric determination of molybdenum

Abstract

The use of silver, mercury, tin(II) and amalgamated zinc as reducing agents in the oxidimetric determination of molybdenum was investigated. Cerium(IV), dichromate and metavanadate solutions were used for the titration of the molybdenum(V) solutions. All of the methods, except when molybdenum(V) prepared by reduction with silver was titrated with dichromate, gave satisfactory results. With the Jones reductor three redox systems were used for determining molybdenum(III) and gave equal, satisfactory results.
