Step 1: Balance the unbalanced half oxidation reaction for Pb(s) → Pb2+ (aq) Step 2: Balance the unbalanced half reduction reaction for O2 (aq) + H2O(l)→ OH– (aq) Step 3: Add the two half reactions to give the full redox reaction: Step 4: Identify the oxidizing agent Step 5: Identify the reducing agent   For step 1 and step 2, along with balancing the equations, please show how many electrons are added. For example, for the first half reaction, 2 electrons are added. So how many electrons are added in the second half reaction?

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
