- Conductors are substances that can conduct electricity in a solid or molten state, and are not chemically changed.
- Electrolytes are substances that can conduct electricity either in a molten state or an aqueous solution, as well as undergo chemical changes at the same time.
- Non-electrolytes are substances that cannot conduct electricity either in a molten state or an aqueous solution.
- Electrolysis is the decomposition of a chemical compound into its constituent elements when an electric current passes through an electrolyte.
- An electrolytic cell ia a device that uses electrical energy to generate chemical reactions.
Electrodes are conductors that transmit electricity through the electrolyte during electrolysis.
Cathode is the electrode that is connected to the negative terminal of a battery.
Anode is the electrode through which the electrons leave the electrolyte and move to the external circuit.
Molten compounds or aqueous solutions can conduct electricity due to the presence of free moving ions.
During electrolysis, cations move towards the cathode, where they will be discharged by accepting electrons, whereas anions move towards the anode, where they will be discharged by donating electrons.
A voltaic or galvanic cell is a device that converts chemical energy into electrical energy.
