Which of the following metals is reduced by an electron flow in an electric furnace rather than by chemical reduction?

Question

Quizplus · Accepted Answer

Aluminum is reduced by the Hall-Héroult process, which involves the use of an electric current in an electric furnace to reduce aluminum oxide into pure aluminum. This process is a form of electrolysis where the aluminum oxide is dissolved in a molten cryolite electrolyte, and an electric current is passed through it, causing aluminum ions to be reduced to aluminum metal at the cathode. The other metals listed (iron, copper, and lead) are commonly reduced through chemical reduction using reductants such as carbon or hydrogen gas.
