In the reaction : — Redox Reactions and Volumetric Analysis Chemistry Question
Question
In the reaction $3Br_2 + 6CO_3^{2-} + 3H_2O \rightarrow 5Br^- + BrO_3^- + 6HCO_3^-$:
Answer: D
💡 Solution & Explanation
Bromine ($Br_2$) has an oxidation state of $0$. In $Br^-$, it is $-1$ (reduction). In $BrO_3^-$, let O.S. be $x$: $x + 3(-2) = -1 \Rightarrow x = +5$ (oxidation). Since the same element $Br$ is both oxidized and reduced, it is a disproportionation reaction. [1-34]
