In the electrolysis of aluminum ore, what is the positive ion made of? Give the name, not the symbol. A. Aluminum B. Oxygen C. Hydrogen D. Aluminum oxide

Final answer: The positive ion in the electrolysis of aluminum ore is aluminum, which is reduced at the cathode to produce aluminum metal. Option A Explanation: In the electrolysis of aluminum ore, specifically bauxite, the positive ion is composed of aluminum. This is because during electrolysis, the ore is first converted into pure aluminum oxide (Al2O3) by the Bayer Process. This compound contains aluminum ions, which have a positive charge, and oxide ions with a negative charge. When electrolysis is performed, aluminum ions are reduced at the cathode to form aluminum metal, as shown by the half-reaction Al3+ + 3e- → Al. The other ions, such as oxide, are not involved in the reduction at the cathode. The question given refers to the positive ion during the electrolysis of aluminum ore, thus the correct answer is A. Aluminum. When a current of 25.0 A is passed through the solution for 15.0 minutes, aluminum metal is recovered at the cathode by reduction of aluminum ions. Option A
