Question

During the process of electrolytic refining of copper, some metals present as impurity settle as ‘anode mud’. These are(a) Fe and Ni(b) Ag and Au(c) Pb and Zn(d) Sn and Ag

Answer 1

During the process of electrolytic refining of copper. In the electrolytic refining of copper the more electropositive impurities like Fe, Zn, Ni, Co, etc. dissolve in the solution and less electropositive impurities such as Ag, Au and Pt collect below the anode in the form of anodic mud.

Thus, (b) is the correct answer.
