- Electrolysis is a chemical process where a substance in its molten state or in an aqueous solution decomposed by electric current.
- This involves conversion of energy from electrical energy to chemical energy.
- Electrodes are the strips of metals inserted into electrolyte for conduction of electricity. he metal electrode connected to the positive terminal of the battery is called the anode (+). The metal electrode connected to the negative terminal of the battery is called the cathode (-).
- Electrolytic cell is the complete set-up for electrolysis. This consists of the vessel containing the electrolyte, anode, cathode, battery and wires.
