A voltaic cell is made by connecting two half cells represented by half equations below : $\displaystyle \mathrm{Sn}^{2+}{ }_{(\mathrm{aq})}+2 \mathrm{e}^{-} \rightarrow \mathrm{Sn}_{(\mathrm{s})} \mathrm{E}^{\circ}=-0.14 \mathrm{~V}$ $\displaystyle \mathrm{Fe}^{3+}{ }_{(\mathrm{aq})}+\mathrm{e}^{-} \rightarrow \mathrm{Fe}^{2+}{ }_{(\mathrm{aq})} \mathrm{E}^{\circ}=+0.77 \mathrm{~V}$ Which statement is correct about this voltaic cell ?
Official answer
From CBSE’s own marking scheme for this paper.
(B)
Sn is oxidised and the voltage of the cell is $\displaystyle 0.91$ V
