Question

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. iodide is oxidised
• C. sulphur is reduced
• D. $H_2O$ is one of the products

Answer 1

Answer: (D)

$H_2O$ is one of the products

Answer 2

The balanced equation is,
$ClO _{3}^{-}+6 I ^{-}+6 H _{2} SO _{4} \longrightarrow 3 I _{2}+ Cl ^{-}+6 HSO _{4}^{-}+3 H _{2} O$
