Vanadium compounds are compounds formed by the element vanadium (V). The chemistry of vanadium is noteworthy for the accessibility of the four adjacent oxidation states 2–5, whereas the chemistry of the other group 5 elements , niobium and tantalum , are somewhat more limited to the +5 oxidation state.

Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t 2g orbitals.
Vanadium(II) chloride – VCl 2; Vanadium(III) ... Sodium hydrogen carbonate (Sodium bicarbonate) – NaHCO 3; Sodium hydrosulfide – NaSH; Sodium hydroxide – NaOH;
Vanadium compounds are used extensively as catalysts; [83] Vanadium pentoxide V 2 O 5, is used as a catalyst in manufacturing sulfuric acid by the contact process [84] In this process sulfur dioxide (SO 2) is oxidized to the trioxide (SO 3): [23] In this redox reaction, sulfur is oxidized from +4 to +6, and vanadium is reduced from +5 to +4:

The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
Technical grade V 2 O 5 is produced as a black powder used for the production of vanadium metal and ferrovanadium. [10] A vanadium ore or vanadium-rich residue is treated with sodium carbonate and an ammonium salt to produce sodium metavanadate, NaVO 3. This material is then acidified to pH 2–3 using H 2 SO 4 to yield a precipitate of "red ...
This hygroscopic blue solid is one of the most common sources of vanadium in the laboratory, reflecting its high stability. It features the vanadyl ion, VO 2+, which has been called the "most stable diatomic ion". [1] Vanadyl sulfate is an intermediate in the extraction of vanadium from petroleum residues, one commercial source of vanadium. [2]
