A) cathode
B) electrode
C) cathode mud
D) anode mud
Correct Answer: D
Solution :
Blister copper obtained from the Bessemer convenor is purified first by poling to get 99.5% pure copper and then the electrolytic refining to get copper of very high purity (99.95%-99.99%). Impure copper usually contains Ag, Au, Ni, Zn, Fe, Pb, Sn etc., as impurity. Impure metal is taken as anode dipped in the acidified solution of \[CuS{{O}_{4}}.\]The impurities of Ni, Fe and Zn pass into solution as sulphate while impurities of Ag, Au and Sn etc. are thrown down as anode mud (below anode).You need to login to perform this action.
