The standard electrode potential (reduction) of Ag+|Ag is 0.800 V at 25°C. Its electrode potential in a solution containing 10–3 M ion of Ag+ ions is
Answer & explanation
Correct answer: option 1
The correct answer is option 1. 0.623 V.
The given cell can be written as
\(Ag^+ + 1e^- \rightarrow Ag\) \(E^o_{cell} = 0.800 V\)
\(E_{cell} = E^o_{cell} − \frac{0.0591}{1}log \frac{1}{[Ag^+]}\)
\(E_{cell} = 0.8 − \frac{0.0591}{1}log\frac{1}{10^{−3}}\)
\(E_{cell} = 0.623 V\)
