A “dead” 12-Volt lead/acid storage battery has 4.30 g of PbSO4 (molar mass = 303.3 g), deposited on its electrodes. To recharge it, a “trickle charger” is attached to the Pb anode that supplies 0.120 amperes of current at a voltage of 13.0 V. Calculate how much time it would take to convert all the PbSO4back into SO42− ions in solution. Enter your answer in hours.

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.
