/Mn2+ = 1.51 V, Eo Cr3+/Cr = -0.74 VEMF of Daniell cell was found using different concentrations of Zn2+ion. A graph was then plotted between Ecell and log\(\frac{[Zn^{2+}]}{[Cu^{2+}]}\). The plot was found to be linear with an intercept of \(E_{cell}\) axis equal to 1.10 V. Ecell for Zn/Zn2+ (0.1 M)||Cu2+(0.01 M)| Cu will be:
1. 1.10 V
2. 1.0705 V
3. 0.93 V
4. 0.078 V
