Question

The standard electrode potentials of Zn, Ag and Cu are \(-0.76\), \(+0.80\) and \(+0.34\text{ V}\) respectively. Identify the correct statement from the following.

• A. Ag can oxidize Zn and Cu
• B. Ag can reduce \(Zn^{2+}\) and \(Cu^{2+}\)
• C. Zn can reduce \(Ag^+\) and \(Cu^{2+}\)
• D. Cu can oxidize Zn and Ag

Hint:

Lower reduction potential means stronger reducing agent. Zinc has the lowest \(E^\circ\), so it can reduce \(Ag^+\) and \(Cu^{2+}\).

Answer 1

The Correct Option is C
