Standard electrode potential data are useful for understanding the suitability of an oxidant in a redox titration. Some half cell reactions and their standard potentials are given below :
\(\mathrm{MnO}_{4(a q)}^{-}+8 \mathrm{H}_{(a q)}^{+}+5 e^{-} \rightarrow \mathrm{Mn}_{(a q)}^{2+}+4 \mathrm{H}_{2} \mathrm{O}_{(l)}\)
; E° = 1.51 V
\(\mathrm{Cr}_{2} \mathrm{O}_{7(a q)}^{2-}+14 \mathrm{H}_{(a q)}^{+}+6 e^{-} \rightarrow 2 \mathrm{Cr}_{(a q)}^{3+}+7 \mathrm{H}_{2} \mathrm{O}\)
; E° = 1.38 V
\(\mathrm{Fe}_{(a q)}^{3+}+e^{-} \rightarrow \mathrm{Fe}_{(a q)}^{2+}\) ; E° = 0.77 V
\(\mathrm{Cl}_{2(g)}+2 e^{-} \rightarrow 2 \mathrm{Cl}_{(a q)}^{-}\); E° = 1.40 V
Identify the only incorrect statement regarding the quantitative estimation of aqueous Fe(NO₃)₂.
