ELECTROLYSIS = a chemical change caused by passing an electric current through a compound which is molten or in solution.
ELECTROLYTE = a substance that undergoes electrolysis. Electrolytes all contain ions.
PANC = Positive Anode Negative Cathode.
positive ions = CATIONS (because they are attracted to the cathode).
Positive ions move to the cathode where they are discharged by gaining electrons.
negative ions=ANIONS (because they are attracted to the anode)
Negative ions move to the anode where they are discharged by giving electrons to the electrode.
Remember OILRIG (Oxidation Is Loss, Reduction Is Gain of electrons)
