Electrolysis

The electrical circuit has two electrodes that makes contact with the electrolyte.

The ions in the electrolyte move to the electrodes where the are discharged to produce elements.

The Metal is formed at the negative electrode. The Non-Metals formed at the positive electrode. An easy way to remember this in terms of electrons is:

Oxidation

Is

Loss of electrons

Reduction

Is

Gain of electrons
