Question

Identify the correct statement with respect to the following reaction.

$2K_{2}MnO_{4} + Cl_{2} \rightarrow 2KCl + 2KMnO_{4}$

• A. Oxidation of potassium manganate is taking place.
• B. Reduction of potassium manganate is taking place.
• C. Oxidation of $Cl_{2}$is taking place.
• D. $Cl_{2}$acts as reducing agent in the reaction.

Answer 1

Answer: (A)

Oxidation of potassium manganate is taking place.

Answer 2

: $2K_{2}\overset{+ 6}{M}nO_{4} + \overset{0}{Cl_{2}} \rightarrow 2K\overset{- 1}{Cl} + 2K\overset{+ 7}{M}nO_{4}$

$Mn \rightarrow$Increase in oxidation number hence oxidation.

$Cl_{2} \rightarrow$ Decrease in oxidation number hence reduction

$Cl_{2}$ is acting as an oxidizing agent.
