GCSE EDEXCEL Electrolytic Processes Definitions

Electrolyte is the term used to describe the ionic compound (molten or aqueous solution) that conducts the electricity.

Electrolysis : When an electric current is passed through an electrolyte it decomposes or breaks down.

Electrode is a rod of metal or graphite through which an electric current flows into or out of an electrolyte.

Anode is the positive electrode of an electrolysis cell.

Anion is a negatively charged ion which is attracted to the anode.

Cathode is the negative electrode of an electrolysis cell.

Cation is a positively charged ion which is attracted to the cathode.
