- Cathode or negative electrode is connected to the negative terminal of the battery. Cathode will attract positive ions or cations. Reduction takes place at the cathode, as the cation gains electrons.
- Anode or positive electrode is connected to the positive terminal of the battery. Anode will attract negative ions or anions. Oxidation takes place at the anode, as the anion loses electrons.
- An inert electrode (e.g graphite, and platinum) is one that does not react. A reactive electrode is one that will react.
- A typical experimental setup for electrolysis is represented by the diagram below:
