Step 1 of 6

Given

\(\begin{array}{l}
V\left(\mathrm{CuSO}_{4}\right)=25.0 \mathrm{ml} \\
C\left(\mathrm{CuSO}_{4}\right)=0.20 \mathrm{M} \\
V\left(\mathrm{ZnSO}_{4}\right)=25.0 \mathrm{ml} \\
C\left(\mathrm{ZnSO}_{4}\right)=0.20 \mathrm{M} \\
V \rightarrow \text { volume } \\
C \rightarrow \text { concentration }
\end{array}\)

Standard reduction potential at \(25^{\circ} \mathrm{C}\) for pair \(\mathrm{Cu}^{2+} / \mathrm{Cu} \text { is } 0.34 \mathrm{~V}\).

Standard reduction potential at \(25^{\circ} \mathrm{C}\) for pair \(\mathrm{Zn}^{2+} / \mathrm{Zn} \text { is }-0.76 \mathrm{~V}\).

The more positive \(E^{\circ}\) value is, the greater the tendency for the substance to be reduced.

By the standard reduction potential at \(25^{\circ} \mathrm{C}\) 

Hence we can say copper is the cathode and zinc is the anode.
