Fused Bauxite is electrolyzed to get:
Correct answer: C. Aluminum
- A. Sodium
- B. Magnesium
- C. Aluminum
- D. lron
Explanation
Option A) Sodium is not obtained by electrolysis of fused bauxite. Sodium is usually obtained by the electrolysis of molten sodium chloride (NaCl).Option B) Magnesium is not obtained by the electrolysis of fused bauxite. Magnesium is usually obtained by the electrolysis of molten magnesium chloride (MgCl2).Option C) The bauxite is purified to yield a white powder- aluminium oxide (also known as alumina)-from which aluminium can be extracted. The extraction is done by electrolysis, but first, the aluminium oxide must be melted so that electricity can pass through it. Option D) Iron is not obtained by the electrolysis of fused bauxite. Iron is usually obtained from iron ore through processes such as smelting and reduction of carbon.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
