Answer»

`SO_(2)` GAS has oxidisingas well as reducingbehaviour .
`D_(2)O` reacts slowlythan ` H_(2)O` in chemicalreactions
`KI_(s)`reacts with conc.`H_(2)SO_(4)`to produce HI
`O_(3)`oxidises KI to `I_(2)`of the given reaction is

SOLUTION :`2KI + H_(2)SO_(4) to K_(2)SO_(4) + 2HI`
` 2HI + H_(2)SO_(4) to2 H_(2)O + SO_(2) + I_(2)`
