Q6 of 32 Page 163

Name the common elements present in the anode mud in electrolytic refining of copper. Why are they so present?

The common elements present in anode mud in electrolytic refining are antimony, selenium, tellurium, silver, gold, and platinum. These elements being less reactive, are not affected by CuSO4 + H2SO4 solution and hence settle down under anode as anode mud.
