Question

Which of the following statement is wrong? In the reaction $2KCl{O}_3+I_2\to 2KI{O}_3+{Cl}_2$?

• A. ${Cl}_2$ is more reactive than $I_2$
• B. When $KCl{O}_3$ reacts with $I_2$, ${Cl}_2$ is liberated
• C. $KCl{O}_3+I_2$ is a redox reaction and $I_2$ is oxidized
• D. In the above reaction, $I_2$ is reduced

Answer 1

The correct option is D In the above reaction, $I_2$ is reduced

the given reaction is

${2KClO}_3+I_2\to {2KIO}_3+{Cl}_2$

in reactant,oxidation state of iodine in $I_2=0$

in product,oxidation state of iodine in${IO}_3^{-}$is 3

so,oxidation state of iodine change from 0 to5,so it is oxidlsed.
