Electrolysis

• Molten • Aqueous • Other options do not work as opposite charges need to be free to move around for the current to complete the circuit

Something that does not conuct electricity such as covalent substances

• 2 electrolytes • Cathode and anode • Negative, positive • Reduction, oxidisation

Ions in the elctrolyte move to the electrode where they either lose or gain electrons to become elements and are discharged

• If the electrolyte is molten the positive metal ion is discharged at the cathode and the negative non-metal ion is discharged at the anode • If the elctrolyte is in solution then group 1 or 2 metal converts to hydrogen • The product at the anode is either oxygen or a halogen, families gets converted to oxygen

• The break-down of a substance by electricity • The way highly reactive metals are extracted from their compounds • Electrolytes are substances that don’t conduct electricity when solid but when molten or dissolved in water

Reactants at cathode and anode, hydrogen and hydroxide

96500 coulombs, 1 mole of electrons.
