Common mistakes

  • Confusing oxidation and reduction

    Students often confuse oxidation (loss of electrons) with reduction (gain of electrons).

    Fix itRemember that oxidation is associated with an increase in oxidation state, while reduction corresponds to a decrease.

  • Confusing oxidation with reduction

    Students often confuse oxidation (loss of electrons) with reduction (gain of electrons).

    Fix itRemember that oxidation involves an increase in oxidation state, while reduction involves a decrease.

  • Confusing color changes with oxidation states

    Students often attribute color changes solely to oxidation state changes without considering ligand effects.

    Fix itAlways consider both the oxidation state and the ligand field strength when explaining color changes.
