MCQ
For the reaction:

$I ^{-}+ ClO _3^{-}+ H _2 SO _4 \longrightarrow Cl ^{-}+ HSO _4^{-}+ I _2$

The correct statement(s) in the balanced equation is/are:

$(A)$ Stoichiometric coefficient of $HSO _4^{-}$is 6 .

$(B)$ lodide is oxidized.

$(C)$ Sulphur is reduced.

$(D)$ $H _2 O$ is one of the products.

  • A
    $(A,B,C)$
  • $(A,B,D)$
  • C
    $(A,C,D)$
  • D
    $(B,C,D)$

Answer

Correct option: B.
$(A,B,D)$
b
$6 I ^{-}+ ClO _3^{-}+6 H _2 SO _4 \rightarrow Cl ^{-}+6 HSO _4^{-}+3 I _2+3 H _2 O$

Hence, $I ^{-}$is oxidised to $I _2$

Coefficient of $HSO _4^{-}=6$

and $H _2 O$ is one of the product.

Hence $(A),(B),(D)$
