Q1 / 150 · MHT CET 2021 (23 Sep Shift 2) · Chemistry

In the cell represent as $\mathrm{Ni}_{(\mathrm{s})}\left|\mathrm{Ni}_{(\mathrm{MM})}^{2^{\oplus}}\right|\left|\mathrm{Ag}_{(\mathrm{IM})}^{\oplus}\right| \mathrm{Ag}_{(\mathrm{s})}$, the reducing agent is

  • A
    $\mathrm{Ag}$
  • B
    $\mathrm{Ag}^{\oplus}$
  • Correct answer
    C
    $\mathrm{Ni}$
  • D
    $\mathrm{Ni}^{2 \oplus}$

Solution

Anode Half cell: $\mathrm{Ni}_{(\mathrm{s})} \stackrel{\text { Oxidation }}{\longrightarrow} \mathrm{Ni}^{2+}+2 \mathrm{e}^{-}$ Cathode Half-cell, $\mathrm{e}^{-}+\mathrm{Ag}^{+} \stackrel{\text { Reduction }}{\longrightarrow} \mathrm{Ag}_{(\mathrm{s})}$ Reducing Agent is $\mathrm{Ni}_{(\mathrm{s})}$

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