Electrolytic cells use electricity to cause a nonspontaneous redox reaction to occur. An electrolytic cell is constructed using the following components: . a power source, such as a battery, • the substance that will undergo electrolysis, and • two inert electrodes (usually platinum), which serve as the electrical connection between the power source and the substance undergoing electrolysis. As with any cell, oxidation occurs at the anode and reduction occurs at the cathode. The oxidation of water, which produces oxygen...

2. You measured cell potentials (voltages) for reactions of metals and metal ions. We will use the standard date and practice calculating these. Recall: E-Ecathode - Eanode Remember reduction occurs at the cathode; oxidation occurs at the anode For the anode reactions, your reactant will be on the product side of the standard equation, but don't change any sign. The equation does that for you. Cathode Reaction Agt + e → Ag Ecathode Anode Reaction...
