What are the different ways of doing: 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
What is a: Non-electrolyte
Something that does not conuct electricity such as covalent substances
How many: Electrolytes in a circuit, what are they called and negative/positive
• 2 electrolytes • Cathode and anode • Negative, positive • Reduction, oxidisation
What happens in: Electrolysis
Ions in the elctrolyte move to the electrode where they either lose or gain electrons to become elements and are discharged
Rules of: Electrolysis
• 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
What is: Electrolysis
• 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
What is produced when reacting: Brine
Reactants at cathode and anode, hydrogen and hydroxide
What is a: Faraday
96500 coulombs, 1 mole of electrons.
