3 K overset text +5 IO3 + 3 SO3 arrow 3 K overset text -1 I + 3SO3 During this reaction, O.N. of iodine changes from + 5 in KIO3 to - 1 in KI.

Q. When $S O_{2}$ is passed through a solution of potassium iodate, the oxidation state of iodine changes from

+5 to 0

+5 to -1

- 5 to 0

- 7 to -1

$3 K I +5 O_{3} + 3 S O_{3} \to 3 K I -1 + 3 S O_{3}$
During this reaction, O.N. of iodine changes from $+ 5$ in $K I O_{3}$ to - $1$ in $K I$ .
