Vedclass · Answer

(A) In an electrochemical cell,the electrode where oxidation occurs is called the $Anode$,and the electrode where reduction occurs is called the $Cathode$. In a $Galvanic$ cell,the $Anode$ is the negative electrode and the $Cathode$ is the positive electrode. In an $Electrolytic$ cell,the $Anode$ is the positive electrode and the $Cathode$ is the negative electrode. However,by standard convention in general electrochemistry,the $Anode$ is defined as the site of oxidation and the $Cathode$ as the site of reduction. Given the options,$A$ describes the standard $Electrolytic$ cell configuration.
