The standard electrode potential for a half-reaction is the potential difference measured under standard conditions: 1 M concentration, 1 atm pressure, and 25°C.
Step 1: Examine the provided half-reaction
The half-reaction presented is:
\[
Ag^+ + e^- \rightarrow Ag(s)
\]
The standard electrode potential for this specific half-reaction is a recognized electrochemical value, determined to be:
\[
E^\circ = +0.80 \, \text{V}
\]
Answer: Consequently, the standard electrode potential for the reduction of \(Ag^+\) to \(Ag\) is \(+0.80 \, \text{V}\). Option (1) is the correct choice.
