oxidized. In this electrochemical cell, what is the role of the Cu electrode, that is submerged in a solution of CuSO4?
Answer: The Cu electrode in this electrochemical cell functions as the cathode. During the reaction, Cu2+ ions from the CuSO4 solution gain electrons from the Zn electrode and are reduced to form solid Cu at the cathode. The overall reaction can be represented as:
Zn (s) + Cu2+ (aq) → Zn2+ (aq) + Cu (s)
The Cu electrode acts as a site for the reduction reaction to occur, while the Zn electrode is the site of the oxidation reaction.
The Zn electrode is chipped in a solution containing znso4 and gives off electrons it is therefore
