Electrolysis and what half equations show

Electrolysis cell with cathode and anode labelled, cations moving to the cathode, anions moving to the anode, and example half equations at each electrode

Electrolysis uses electricity to break down a molten or aqueous ionic substance. Ions move through the electrolyte, while electrons move through the wires and electrodes. Cations move to the negative cathode and anions move to the positive anode.
