Anode: Positive electrode. Attracts negative anions.
Anions: Negatively charged ions
Cathode: Negative electrode. Attracts positive cations.
Cations: Positively charged ions
Electrode: A conductor placed in an electrolyte to electrolyse it
Electrolysis: The process by which a molten or aqueous ionic compound is separated by passing a current through.
Electrolyte: A molten or aqueous ionic compound that conducts electricity.
Half equation: An ionic half equation includes only half a chemical reaction, it just shows what is happening at the individual electrodes with the transfer of electrons.
