Question

Given $E_{A{g}^{+}/Ag}^{\circ }=+0.80V;E_{C{u}^{2+}/Cu}^{\circ }=+0.34V;$
$E_{F{e}^{3+}/F{e}^{2+}}^{\circ }=+0.76V;E_{C{e}^{4+}/C{e}^{3+}}^{\circ }=+1.60V$
Which of the following statements is not correct?

• A. $F{e}^{3+}$ does not oxidise $C{e}^{3+}$.
• B. $Cu$ reduces $A{g}^{+}$ to $Ag$.
• C. $Ag$ will reduce $C{u}^{2+}$ to $Cu$.
• D. $F{e}^{3+}$ reduces $C{u}^{2+}$ to $Cu$.

Answer 1

Answer: (C)

Since $Ag$ has higher reduction potential than $Cu$, $Ag$ will not reduce $C{u}^{2+}$ to $Cu$. $Cu$ can reduce $A{g}^{+}$ to $Ag$.
