Question

$O _3$ is estimated by $I ^{-}$in iodometric method. Balanced reaction is

• A. $2 H ^{+}+ O _3+2 I ^{-} \rightarrow I _2+ O _2+ H _2 O$
• B. $2 I ^{-}+ O _3+ H _2 O \rightarrow I _2+ O _2+2 OH ^{-}$
• C. Both (a) and (b)
• D. None of the above

Answer 1

Answer: (C)

$O _3$ can be estimated iodometrically in acidic and basic medium both $l ^{-}$is oxidized to $l _2$
