Answer»

Electrolysis is the process of using electricity to break apart the ions in an ionic substance that is either dissolved in water or molten. Half equations can be used to explain what happens to the ions during electrolysis. Electrolysis is often used to obtain chlorine, hydrogen, sodium hydroxide and to purify sodium and copper metals.

Positively charged ions migrate to the negative electrode (cathode) during electrolysis. They gainelectronsand arereduced.

Negatively charged ions migrate to the positive electrode (anode) during electrolysis. They lose electrons and areoxidised.
