MCQ
In redox reaction $\text{Cu}_\text{(s)}+2\text{Ag}^+\text{(aq)}\xrightarrow{\ \ \ \ \ \ \ \ \ }\text{Cu}^{2+}\text{(aq)}+2\text{Ag}$ the weakest oxidising agent and weakest reducing agents are :
  • $\mathrm{Cu}^{2+}$ and $\ce{Ag}$ respectively.
  • B
    $\ce{Ag}$ and $\mathrm{Cu}^{2+}$ respectively.
  • C
    $\mathrm{Ag}^{+}$and $\mathrm{Cu}^{2+}$ respectively.
  • D
    $\mathrm{Ag}^{+}$and $\mathrm{Cult}^{2+}$ respectively.

Answer

Correct option: A.
$\mathrm{Cu}^{2+}$ and $\ce{Ag}$ respectively.
$\ce{Cu^{2+}}$ and $\ce{Ag}$ are weakest oxidising and reducing agents respectively because $\ce{Cu^{2+}}$ cannot gain electron easily and $\ce{Ag}$ cannot lose electron easily in above reaction.
