Pervanadyl
Pervanadyl is jargon that has two meanings.
- Pervanadyl can refer to aquo complexes containing. This pale yellow oxycation of vanadium(V) is the predominant vanadium species in acidic solutions with pH between 0 and 2. Like permanganate, pervanadate features the metal in its highest oxidation state.
- Pervanadyl also can refer to peroxo derivatives of vanadium which are often abbreviated. Several vanadium peroxides have been characterized.
The ion can form a complex with a single aminopolycarboxylate ligand, or with tridentate Schiff base ligands.
The / redox couple is used at the cathode of the vanadium redox battery. The standard [reduction potential] of this couple is +1.00 V.
