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






Answer :



In electrolytic refining of copper, the common elements present in anode mud are
selenium, tellurium, silver, gold, platinum, and antimony.



These elements are very less reactive and are not affected during the
purification process. Hence, they settle down below the anode as anode mud.
