(A) In the electrolytic refining of aluminum (Hoopes process),the cell consists of three layers of molten liquids of different densities. The bottom layer is molten impure aluminum which acts as the anode. The middle layer consists of molten fluorides of $Al, Ba,$ and $Na$. The top layer is molten pure aluminum which acts as the cathode. During electrolysis,$Al^{3+}$ ions from the middle layer are reduced at the cathode to form pure $Al$.

In the electrolytic refining of aluminum,what is the product obtained at the cathode?
