Q29 / 160 · AP EAMCET 2024 (19 May Shift 2) · Chemistry

In neutral medium potassium permanganate oxidises $F$ to X. Identify the X

  • A
    Iodine
  • Correct answer
    B
    Iodate
  • C
    Periodate
  • D
    Hypoiodite

Solution

In neutral or faintly alkaline medium, iodide ion oxidised to iodate in as: $2 \mathrm{MnO}_4^{-}+\mathrm{H}_2 \mathrm{O}+\mathrm{I}^{-} \rightarrow 2 \mathrm{MnO}_2+2 \mathrm{OH}^{-}+\mathrm{IO}_3^{-}$ (Iodate ion)

Hence, the correct answer is option: 'B'.
