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 6 of 6
