The tendencies of the electrodes made up of $\mathrm{Cu}$, $\mathrm{Zn}$ and $\mathrm{Ag}$ to release electrons when dipped in their respective salt solutions decrease in the order

  • A
    $\mathrm{Zn}>\mathrm{Ag}>\mathrm{Cu}$
  • B
    $\mathrm{Zn}>\mathrm{Cu}>\mathrm{Ag}$
  • Correct answer
    C
    $\mathrm{Cu}>\mathrm{Zn}>\mathrm{Ag}$
  • D
    $\mathrm{Ag}>\mathrm{Cu}>\mathrm{Zn}$

Solution

Reducing character i.e tendency to loose electron decreases down the series, hence the correct order is $\mathrm{Zn}>\mathrm{Cu}>\mathrm{Ag}$

Hence, the correct answer is option: 'C'.
