What is the direction of current in following galvanic cell?


$\begin{array}{1 1}(A)\;Cu\;electrode\; to\; Zn\; electrode\\(B)\;Zn\;electrode\;to \;CO\;electrode\\(C)\;Sometimes\;Cu\;to\;Zn\;and\;sometimes\;Zn\;to\;Cu\\(D)\;None\end{array}$

1 Answer

By electrochemical series
So Cu electrode behave as cathode and Zn as anode.So current flows from Cu to Zn electrode.
Hence (A) is the correct answer.
