If \(\mathrm{Sn}^{2+}+2 \mathrm{e}^{-} \rightarrow \mathrm{Sn} ;\) \(\mathrm{E}^{0}=-0.14 \mathrm{~V}\)
\(\mathrm{Sn}^{4+}+2 \mathrm{e}^{-} \rightarrow \mathrm{Sn}^{2+}\) \(\mathrm{E}^{0}=+0.13 \mathrm{~V}\) then:
\(\mathrm{Sn}^{4+}+2 \mathrm{e}^{-} \rightarrow \mathrm{Sn}^{2+}\) \(\mathrm{E}^{0}=+0.13 \mathrm{~V}\) then:
- Sn2+ will disproportionates to Sn4+and Sn
- Sn2+ is stable and it will not disproportionate
- Sn4+ is easily reduced to Sn
- none of the above
Answer
(B) Sn 2+ is stable and it will not disproportionate
