Complete and balance the following redox equation using the set of smallest whole?number...

Below is the reaction has been given:

{eq}Br_2 (aq) + Sb^{3+}(aq) \rightarrow Br^-(aq) + Sb^{5+} {/eq}

Oxidation half reaction

{eq}Sb^{3+}(aq) \rightarrow Sb^{5+} {/eq}

Balancing oxidation half-reaction:

{eq}Sb^{3+}(aq) \rightarrow Sb^{5+} + 2e^- {/eq}

Reduction half reaction

{eq}Br_2 \rightarrow 2Br^- {/eq}

Balancing reduction half-reaction:

{eq}Br_2 + 2e^- \rightarrow 2Br^- {/eq}

Adding both the equation we get,

{eq}Br_2 (aq) + Sb^{3+}(aq) \rightarrow 2Br^-(aq) + Sb^{5+} {/eq}

• The sum of the coefficient is 5, so None of these is the correct option.
