Purification of aluminum by electroysic refiering is known as

Options

A. Hall's process
B. baryor's process
C. Hoope's process
D. Sepeck's process

Answer

c

Explanation

Parification of al os done electrolytivcally by hoope's process .The refining cell considers of threre fushed lapuse (i) in the bottom mode inyer of `AI,C` and `Si,`(ii) the middle layer of cryoints haruim flonrede and (ii) the top cathode layer of the piure metal .THe electrolyist cell is made of an iron box lined with carbon when ,the current flows , Ai which rises from the fused mixture are dischanged at the cathont floes as pure Ai which rise to the surface at the semetimes an equivalent mount of Ai from the allow gfoes into solution in the middle layer containing the electroyle The impuries of C are remain beloe.
