WebNov 3, 2015 · Step 1: Now you need to find out how many electrons are needed for each of these reactions, which you have correctly done. Step 2: Then you balance each reaction with respect to both mass and charge. To balance for oxygen, you add water on the oxygen-deficit side. Then you can add protons to balance for hydrogen. Webelectrochemical cells. For example the reaction, Zn(s) + Cu 2+ (aq) → Zn 2+ (aq) + Cu (s), can be separated into two half-reactions that form the basis of the electrodes in an electrochemical cell. The electrodes in an electrochemical cell are called the cathode and anode : cathode: Cu 2+ (aq) + 2 e – → Cu (s) reduction
