WebLearn about and revise electrolysis with this BBC Bitesize GCSE Chemistry (AQA) study guide. WebKidzSearch Safe Wikipedia for Kids. Electrolysis is a scientific way of 'splitting' substances. Electrolysis means 'electric-splitting' and involves the separation of substances through an electric current. Metals above carbon in the reactivity series ( potassium, sodium, lithium, calcium, magnesium and aluminium) are extracted by electrolysis.
WebElectrolysis: General Principles. When an electric current is passed through a molten ionic compound the compound decomposes or breaks down. The process also occurs for … WebThe topic will cover the following lesson points based on the syllabus objectives: Define electrolysis as the process of breaking down an ionic substance, whether it is molten or …

Electrode Examples. WebKey terms. Electrode is a rod of metal or graphite through which an electric current flows into or out of an electrolyte. Electrolyte is the ionic compound in molten or dissolved solution that conducts the electricity. Anode is the positive electrode of an electrolysis cell. Anion is a negatively charged ion which is attracted to the anode.
