What is the function of the anode in electrorefining copper?
A.Impure copper oxidizes and dissolves as Cu²⁺
B.Pure copper deposits on it
C.It collects electrons from the supply
D.It does not participate chemically
Explanation
Core Concept
The impure anode is oxidized to Cu²⁺, which migrates and plates as pure copper at the cathode. Impurities fall away as anode sludge.
Correct Answer
AImpure copper oxidizes and dissolves as Cu²⁺
