Oxidants: Fe3+ + 3e- arrow Fe N5+ + 2e- arrow N3+ S6+ + 2e- arrow S4+ These three cannot be oxidised because they are having their maximum oxidation state. Na and I- cannot accept electrons so they cannot act as oxidant.

Oxidants : $F e^{3 +} + 3 e^{-} \to F e$
$N^{5 +} + 2 e^{-} \to N^{3 +}$
$S^{6 +} + 2 e^{-} \to S^{4 +}$
These three cannot be oxidised because they are having their maximum oxidation state. $N a$ and $I^{-}$ cannot accept electrons so they cannot act as oxidant.

Oxidants : Fe3++3e−→Fe N5++2e−→N3+ S6++2e−→S4+ These three cannot be oxidised because they are having their maximum oxidation state. Na and I− cannot accept electrons so they cannot act as oxidant.
