25 6.2 Behaviour of an agent according to its oxidation number
- Central atom at its maximum oxidation number → oxidizing agent only: K₂Cr₂O₇ (Cr +6), HNO₃ (N +5), H₂SO₄ (S +6), KMnO₄ (Mn +7).
- Central atom at its minimum oxidation number → reducing agent only: NH₃ (N −3), CH₄ (C −4), H₂S (S −2), H₂.
- Central atom at an intermediate oxidation number → can be either, depending on the reaction: HNO₂ (N +3), SO₂ (S +4), H₂O₂ (O −1).
