Question:

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.
