Question
Name the common elements present in the anode mud in electrolytic refining of copper. Why are they so present?
Advertisements
Solution 1
Selenium, tellurium, silver, gold, and other elements are frequently found in the anode mud during the electrolytic purification of copper. These elements do not change throughout the electrolytic process because they are less reactive than copper.
Solution 2
The common elements present in the anode mud are antimony, selenium, tellurium, silver, gold and platinum. These elements settle down under the anode as anode mud because they are less reactive and are not effected by CuSO4 . H2SO4 solution.
