Electrolysis: 'Splitting up using electricity' - Using an electric current to break down an IONIC substance.  - When an ionic substance is melted or dissolved in water, the ions are free to move about within the liquid or solution, passing an electric current through the ionic substance thats molten, (e.g. lead bromide) or in solution breaks them down into ELEMENTS.

 Electrolyte  - the substance broken down by an ionic substance.

During electrolysis:

POSITIVELY charged ions move to the NEGATIVE ELECTRODE (CATHODE) and
