When SO2 is passed through an aqueous solution of I2 , it becomes colourless. This is due to combination of SO2 and I2 as follows SO2+2H2O+I2 arrow H2SO4+2HI

Q. When $S O_{2}$ is passed through an aqueous solution of $I_{2}$ , it becomes colourless. This is due to

bleaching reaction of $S O_{2}$

formation of $HIO_{2}$

combination of $S O_{2}$ and $I_{2}$

formation of $H N O_{3}$

When $S O_{2}$ is passed through an aqueous solution of $I_{2}$ , it becomes colourless. This is due to combination of $S O_{2}$ and $I_{2}$ as follows
$S O_{2} + 2 H_{2} O + I_{2} \to H_{2} S O_{4} + 2 H I$
