Your classmate is correct because this reaction illustrates a redox process where zinc (Zn) is oxidized and loses electrons, while copper ions (Cu²⁺) in copper sulfate are reduced and gain electrons to form solid copper (Cu). In a galvanic cell, an oxidation-reduction reaction occurs spontaneously, generating electrical energy. The flow of electrons from the zinc electrode (anode) to the copper electrode (cathode) is what produces the electric current. Additionally, the movement of ions in the electrolyte (copper sulfate solution) supports the overall cell reaction, further illustrating the principles of a galvanic cell.
Use the reactions to complete the activity.
Zn+CuSO4→ZnSO4+Cu
Zinc ( Zn ) reacts with copper sulfate ( CuSO4 ) to form zinc sulfate ( ZnSO4 ) and copper ( Cu ). A classmate tells you this is a reaction in a galvanic cell. In three to five sentences, describe how you know your classmate is correct?
