In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide (a¹₂03) dissolved in molten cryolite (Na3AlF6), resulting in the reduction of the A¹₂o to pure aluminum. Suppose a current of 830. A is passed through a Hall-Heroult cell for 38.0 seconds. Calculate the mass of pure aluminum produced. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.

Concept explainers

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.
