✦ Synopsis

first studied tllo osidation of vanadyl ion by alkaline fcrricyanidc and adopted this rcdos reaction for the quantitative estimation of vanadium. An nqucous solution of ammonium vanadatc WLLS rcduccd by sull)llur diosidc and the blue vanadyl compound was rcoxidizcd by potassium fcrricyaniclc in strongly alkaline medium. The resulting vanadic acid wns rcmovcd by l>rccipitating as hariurn vnnadatc and the fcrrocyanidc in the filtrate was titrated with a standard solution of pcrmanganate in hydrochloric acid mcclium. This mctliod, howw~'r, ncccssitatccl tllc ;dclition of a minimum
