One of the products formed from the reaction of permanganate ion with iodide ion in neutral aqueous medium is

Options

  1. AI2\mathrm{I}_2
  2. BIO3−\mathrm{IO}_3^{-}
  3. CIO4−\mathrm{IO}_4^{-}
  4. DIO2−\mathrm{IO}_2^{-}

Correct answer

B. IO3−\mathrm{IO}_3^{-}

Step-by-step solution

I−+2MnO4−+H2O→ Neutral solution 2MnO2+IO3−+2\mathrm{I}^{-}+2 \mathrm{MnO}_4^{-}+\mathrm{H}_2 \mathrm{O} \xrightarrow{\text{ Neutral solution }} 2 \mathrm{MnO}_2+\mathrm{IO}_3^{-}+2OH−\mathrm{OH}^{-}
