- Electrolysis
- What is it?
- Electrolysis is the (breaking down) of a liquid by passing an electric current through it.
- What Electrolysis needs
- An electrolyte – the liquid that the electric current flows through
- A negative electrode (the cathode)
- A positive electrode (the anode)
- A power supply
- During electrolysis, ions in the electrolyte move to the electrodes and are discharged there.
- Cations
- Cations are positively charged ions. They are attracted to the cathode (negative electrode)
- You should be able to recognize cations from their chemical formulae, which all have a + sign.
- Anions
- Anions are negatively charged ions. They are attracted to the anode (positive electrode)
- You should be able to recognise anions from their chemical formulae, which all have a – sign
