Abstract
Abstract The possible application of benzoylhydrazine, phenylhydrazine, p -nitrophenylhydrazine, 2,4-dinitrophenylhydrazine, isonicotinic acid hydrazide and semicarbazide as reductimetric titrants has been studied. The stability of these substances in various media has been determined and causes of the stability and changes of titre of the solutions are discussed. Among the compounds investigated, isonicotinic acid hydrazide has been found to be the most suitable titrant, its solutions being stable and permitting the rapid and quantitative reduction of a number of inorganic systems.
