Question

What is the standard electrode potential of a half-reaction in which electrons are transferred from \(Ag^+\) to \(Ag\)?

• A. \(+0.80 \, \text{V}\)
• B. \(+0.34 \, \text{V}\)
• C. \(0 \, \text{V}\)
• D. \(-0.76 \, \text{V}\)

Hint:

The standard electrode potential for the reduction of \(Ag^+\) to \(Ag\) is \(+0.80 \, \text{V}\), which indicates that silver ions are easily reduced to silver metal.

Answer 1

The Correct Option is A

The standard electrode potential of a half-reaction is defined as the potential difference when the half-reaction occurs under standard conditions (1 M concentration, 1 atm pressure, and 25°C). Step 1: Review the given half-reaction The given half-reaction is: \[ Ag^+ + e^- \rightarrow Ag(s) \] The standard electrode potential for this half-reaction is a well-known value in electrochemistry and is given as: \[ E^\circ = +0.80 \, \text{V} \] Answer: Therefore, the standard electrode potential for the reduction of \(Ag^+\) to \(Ag\) is \(+0.80 \, \text{V}\). The correct answer is option (1).
