💡 Solution & Explanation

**Step 1:** $BrO_3^- \rightarrow Br^-$ ($+5$ to $-1$, $n=6$). <br>**Step 2:** $Fe^{2+} \rightarrow Fe^{3+}$ ($+2$ to $+3$, $n=1$). <br>**Step 3:** Cross multiply $n$-factors: $1 BrO_3^-$ and $6 Fe^{2+}$. <br>**Step 4:** Balance oxygen with water (3 $H_2O$) and hydrogen with $H^+$ (6 $H^+$). <br>Final: $1BrO_3^- + 6Fe^{2+} + 6H^+ \rightarrow Br^- + 6Fe^{3+} + 3H_2O$.
