1.	In the Hoope's process for refining of Al the fused materials form three different layers and they remain spearated during electrolysis also. This is because.
Answer» The upper layer is kept attracted by cathode and lower layer is kept attracted by anode. There is special arrangement in cell to keep the layers separate. Three layers have DIFFERENT densities Three layers are maintained at DIFFERENTS temperatures. Solution :In the Hoope's PROCESS for refining of Al, the fused materials form three different layers and they remain SEPARATED during electrolysis because the three layers have different densities.
