Question

The reaction
$3 ClO ^{\ominus}( aq ) \rightarrow ClO _3( aq )+2 Cl ^{\ominus}( aq )$ is an example of

• A. Oxidation
• B. Reduction
• C. Disproportionation
• D. Decomposition

Answer 1

Answer: (C)

$ ClO ^{\ominus} \rightarrow ClO _3^{\ominus}+4 e ^{-} \text {(oxidation) } $
$x-2=-1 x-6=-1 $
$x=+1 x=5$
$2 e ^{-}+ ClO ^{\ominus} \rightarrow Cl ^{\ominus} \text { (reducation) }$
$x=1 \,\,\, \,\,\,\, x=-1$
Hence, disproportionation
