- 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.

- 4.4 Chemical changes
- 4.4.3 Electrolysis
- 4.4.3.4 Electrolysis of aqueous solutions
- The ions discharged when an aqueous solution is electrolysed using inert electrodes depend on the relative reactivity of the elements involved.
- At the negative electrode (cathode), hydrogen is produced if the metal is more reactive than hydrogen. At the positive electrode (anode), oxygen is produced unless the solution contains halide ions when the halogen is produced.
