Sometimes seeing precipitates at the cathode, for 10 points, name this process in which reactions are driven by an electric current.
Faraday's laws can be used to find the mass of a substance altered in this process. The Hall-Heroult process involves dissolving alumina in cryolite and then performing this process. This method was used by Davy to discover potassium, sodium, barium, and calcium, and performing this process on water yields hydrogen and oxygen gas.
