Question
In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide (Al,0,) dissolved in molten cryolite (Na, AlF), resulting
in the reduction of the Al,0, to pure aluminum.
Suppose a current of 940. A is passed through a Hall-Heroult cell for 71.0 seconds. Calculate the mass of pure aluminum produced.
