Topics in Redox Reactions

1

Core ideas and definitions

  • Oxidation and reduction always occur together in a redox reaction.
  • Oxidation was first understood as addition of oxygen or removal of hydrogen; the meaning is now broader.
  • Reduction means removal of oxygen or electronegative element, or addition of hydrogen or electropositive element.
2

Oxidation number rules and special cases

  • In free elements, oxidation number is zero.
  • For a monoatomic ion, oxidation number equals its charge.
  • Oxygen is usually −2 in compounds.
3

Reaction types in redox chemistry

  • Redox reactions are classified as combination, decomposition, displacement, and disproportionation reactions.
  • In a combination redox reaction, elemental substances combine to form one product.
  • In a decomposition redox reaction, one compound breaks into simpler substances, at least one of which is elemental.
4

Key examples and comparative reactivity

  • Zinc displaces copper from copper sulphate solution.
  • Copper displaces silver from silver nitrate solution.
  • The order of reducing tendency among Zn, Cu, and Ag is Zn > Cu > Ag.
