The major compound from which iodine is isolated is
  1. $\mathrm{NaI}$
  2. $\mathrm{NaIO}_{3}$
  3. $\mathrm{NaIO}_{4}$
  4. $\mathrm{I}_{2} \mathrm{O}_5$

Solution

The major compound formed from $\mathrm{I}_2$ isolated as $\mathrm{NaIO}_3$
$\mathrm{NaIO}_3+\mathrm{H}_2 \mathrm{SO}_4 ightarrow \mathrm{NaHSO}_4+\mathrm{HIO}_3, \mathrm{HIO}_3+5 \mathrm{HI} ightarrow 3 \mathrm{H}_2 \mathrm{O}+3 \mathrm{I}_2$ .
