Where does a metal ion form?
The negative electrode
1 of 6
What is needed for electrolysis to work?
The ions must be free to move
2 of 6
Where does a non metal ion form?
The positive electrode (except for hydrogen)
3 of 6
What happens to the negatively charged ions which move to the positive electrode during electrolysiS?
They lose electrons and are oxidised
4 of 6
What happens to the positively charged ions which move to the negative electrodeduring electrolysiS?
They receive electrons and are reduced
5 of 6
What happens during the process of electrolysis?
Ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them
