From left: [V(H 2 O) 6] 2+ (lilac), [V(H 2 O) 6] 3+ (green), [VO(H 2 O) 5] 2+ (blue) and [VO(H 2 O) 5] 3+ (yellow).. 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 vanadium oxides can also be used to produce vanadium(III) chloride. For example, vanadium(III) oxide reacts with thionyl chloride at 200 °C: [15] V 2 O 3 + 3 SOCl 2 → 2 VCl 3 + 3 SO 2. The reaction of vanadium(V) oxide and disulfur dichloride also produces vanadium(III) chloride with the release of sulfur dioxide and sulfur. [15]
Vanadium(V) chloride is the inorganic compound with the formula VCl 5. It is a black diamagnetic solid. The molecules adopt a bioctahedral structure similar to that of niobium(V) chloride .
The complexes [V(CN) 6] 3− and [V 2 Cl 9] 3− are referred to as hexacyanovanadate(III) and nonachlorodivanadate(III), respectively. A simple vanadate ion is the tetrahedral orthovanadate anion, VO 3− 4 (which is also called vanadate(V)), which is present in e.g. sodium orthovanadate and in solutions of V 2 O 5 in strong base ( pH > 13 [ 1
Vanadium chloride may refer to: Vanadium(II) chloride, VCl 2; Vanadium(III) chloride, VCl 3; Vanadium(IV) chloride, VCl 4; Vanadium(V) chloride, VCl 5
Heating a suspension of vanadium pentoxide and phosphoric acid gives VOPO 4 •2H 2 O, isolated as a bright yellow solid. [4] According to X-ray crystallography, the V(V) centers are octahedral, with long, weak bonds to aquo ligands. [5] Reduction of this compound with alcohols gives the vanadium(IV) phosphates.
Chlorates are salts of chloric acid. They contain the (ClO 3 −) anion. The stock naming convention distinguishes four chlorates, based on the oxidation state of the chlorine within the oxyanion. The stock and common names are: Chlorate(I) = Hypochlorite; Chlorate(III) = Chlorite; Chlorate(V) = Chlorate; Chlorate(VII) = Perchlorate
Vanadium(V) oxide is a catalyst in the contact process for producing sulfuric acid. 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
