Electrolysis

Electrolysis Breaks down compounds into simpler structures (used in industrial processes)

Ionic substances are decomposed by an electrical charge being passed through them during electrolysis. 

Ions must be free to move for this to work so the compound must be molten. 

Sodium chloride is dissolved in water, hydrogen and hydroxide ions are present as well as the sodium and chloride ions.

Ion which is selected to discharge at an electrode depends on a number of factors. 

Position of the ion in the electrochemical series affects its ease of discharge at an electrode. 

Metal react, they lose electrons…
