Vedclass · Answer

(A) In an electrochemical cell,the anode is the electrode where oxidation occurs,and the cathode is where reduction occurs. For the $Daniell$ cell $(Zn|Zn^{2+}||Cu^{2+}|Cu)$: $Zn$ acts as the anode (negative electrode) and $Cu$ acts as the cathode (positive electrode). For the $Copper-Silver$ cell $(Cu|Cu^{2+}||Ag^+|Ag)$: $Cu$ acts as the anode (negative electrode) and $Ag$ acts as the cathode (positive electrode). Therefore,the correct configuration is: $Daniell$ cell: Anode $(Zn)$,Cathode $(Cu)$,Positive $(Cu)$,Negative $(Zn)$; $Cu-Ag$ cell: Anode $(Cu)$,Cathode $(Ag)$,Positive $(Ag)$,Negative $(Cu)$.

Identify the anode,cathode,positive electrode,and negative electrode for the $Daniell$ cell $(Zn-Cu)$ and the $Copper-Silver$ $(Cu-Ag)$ cell.
