Vedclass · Answer

(C) The $Hoop$ process is an electrolytic refining method for $Al$. In this cell,three layers of different densities are used. The bottom layer consists of impure $Al$ (highest density),the middle layer consists of a molten mixture of $NaF$,$BaF_2$,and $AlF_3$ (intermediate density),and the top layer consists of pure $Al$ (lowest density). These layers remain separated during electrolysis because they maintain different densities.

In the $Hoop$ process for the refining of $Al$,the molten materials form three different layers and remain separated during electrolysis because ..........
