To calculate the electrode potential of zinc when a zinc rod is dipped in a 0.01 M solution of zinc sulfate at 298 K, we use the Nernst equation:
E = E^\circ - \frac{0.0591}{n} \log \frac{[Zn^{2+}]}{1}
Given data:
- Standard electrode potential: V
- Concentration of : M
- Temperature: K
- Number of electrons transferred:
Step-by-step calculation:
E = -0.76 - \frac{0.0591}{2} \log (0.01)
Since , we have:
\log (0.01) = \log (10^{-2}) = -2
E = -0.76 - \frac{0.0591}{2} \times (-2)
E = -0.76 + \frac{0.0591 \times 2}{2}
E = -0.76 + 0.0591
E = -0.7009 \, V
Final Answer:
The electrode potential of zinc in this solution is V (approximately).
