How many of the following is not oxidised by O_(3) ? KI, FeSO_(4), KMnO_(4), K_(2)MnO_(4)

Answer»


Solution :Ozone does nto oxidizes `KMnO_(4)`. But it oxidizes `K_(2)MnO_(4)`.
`2KI+H_(2)O+O_(3) to 2KOH+I_(2)+O_(2). 2FeSO_(4)+H_(2)SO_(3) +O_(3) to Fe(SO_(4))_(3)+H_(2)O+O_(2)`
`2K_(2)MnO_(4)+H_(2)O+O_(3) to 2KMnO_(4)+2KOH+O_(2), KMnO_(4)+O_(3) to` no reaction.
