    - 1. Chemical changes and structure
      - (c) Oxidising and reducing agents
        The electrochemical series represents a series of reduction reactions.
        The strongest oxidising agents are at the bottom of the left-hand column of the electrochemical series.
        The strongest reducing agents are at the top of the right-hand column of the electrochemical series.
        An ion-electron equation can be balanced by adding appropriate numbers of water molecules, hydrogen ions and electrons.

        Redox
        In a redox reaction, reduction and oxidation take place at the same time.
        Ion-electron equations can be written for reduction and oxidation reactions.
