Oxidation number

Type a formula or an ion: K2Cr2O7, Cr2O7 2-, MnO4-, NH4+ or K4[Fe(CN)6]. Put a known ion in brackets when two elements are unknown. Pick an element to solve for it.

C0

  1. Hydrogen is +1 when bonded to non-metals.
  2. Oxygen is −2 in most compounds.
  3. The oxidation numbers add up to the charge, 0: 12(+1) + 6(−2) + 6x = 0.
  4. 6x = 0, so x = 0.
