InterviewSolution

1.	While Fe3+ is stable, Mn3+ is not stabe in acid solution because: (Mn3++e−→Mn2+, E∘=1.5 V;O2+4H++4e−→2H2O, E∘=+1.23V;Fe3++e−→Fe2+,E∘=0.77V)
Answer» While $F e^{3 +}$ is stable, $M n^{3 +}$ is not stabe in acid solution because: $(M n^{3 +} + e^{-} \to M n^{2 +}, E^{\circ} = 1.5 V; O_{2} + 4 H^{+} + 4 e^{-} \to 2 H_{2} O, E^{\circ} = + 1.23 V; F e^{3 +} + e^{-} \to F e^{2 +}, E^{\circ} = 0.77 V)$
