The reaction of $\mathrm{IO}_{3}^{-}$with $\mathrm{I}^{-}$in aqueous acidic medium results in
(a)$\mathrm{I_2}$ and $\mathrm{H_2O}$
(b)$\mathrm{I_2}$ and $\mathrm{H_2O_2}$
(c)$\mathrm{IO^-}$ and $\mathrm{H_2O}$
(d)$\mathrm{IO}^{-}$and $\mathrm{H}_{2} \mathrm{O}_{2}$
Answer
Answer (as printed): A
Explanation
\[ \mathrm{IO_3^{-}(aq) + 5I^{-}(aq) + 6H^{+}(aq) \rightarrow 3I_2(aq) + 3H_2O(l)} \]
