What is the oxidation state of Vanadium in V2O5 ?

Result
Your answer: —  ·  Correct: D

Explanation

In Vanadium pentoxide (V2O5), the oxidation state of Vanadium can be determined using the principle of electroneutrality, where the sum of oxidation states in a neutral molecule is zero.

  • Oxygen (O) almost always carries an oxidation state of -2 in its compounds.
  • Let the oxidation state of Vanadium (V) be x.
  • The chemical formula V2O5 indicates there are 2 atoms of Vanadium and 5 atoms of Oxygen.
  • The calculation is: 2(x) + 5(-2) = 0.
  • This simplifies to: 2x - 10 = 0, which means 2x = 10.
  • Therefore, x = +5.

Vanadium reaches its maximum oxidation state of +5 in this compound. V2O5 is widely known as an industrial catalyst, most notably in the Contact process for the production of sulfuric acid.
