Vedclass · Answer

(C) In the electrolytic refining of aluminium (Hoopes' process),the cell consists of three layers of fused electrolytes with different densities:$1$. The bottom layer is the anode,which consists of impure aluminium alloyed with copper $(Cu)$ to increase its density.$2$. The middle layer consists of a mixture of fluorides (cryolite $Na_3AlF_6$ and barium fluoride $BaF_2$) which acts as the electrolyte.$3$. The upper layer is the cathode,which consists of pure molten aluminium.Therefore,the correct arrangement is: Bottom layer (Anode of $Al$ and $Cu$ alloy),Middle layer (Cryolite and barium fluoride),Upper layer (Cathode of pure $Al$).
