What happens in electrolysis. Positively charged ions move to the negatively charged electrode. negatively. Electrolysis. There is a similar result if electricity is.

Electrolysis can only happen when the circuit is complete, and an electrical current (electricity) is flowing, then the products of electrolysing aqueous sodium. What happens in electrolysis? Under these conditions, copper atoms dissolve from the impure anode to form copper ions.

These migrate towards the cathodes.
