When `I^(Theta)` is oxidised by `MnO_(4)^(Theta)` in an alkaine medium, `I^(Theta)` converts into

A

`lO_(3)^(-)`

B

`l_(2)`

C

`lO_(4)^(-)`

D

`lO^(-)`

Text Solution

Verified by Experts

The correct Answer is:
A
When `l^(-)` is oxidised by `MnO_(4)^(-)`in alkaline medium`l^(-)`converts into`lO_(3)^(-)`. `{:(2KMnO_(4)+2KOHrarr2K_(2)MnO_(4)+H_(2)O+[O]),(ul(2K_(2)MnO_(4)+2H_(2)Orarr2MnO_(2)+4KOH+2[O])),(2KMnO_(4)+H_(2)O overset("alkaline")rarr2MnO_(2)+2KOH+3[O]),(Kl+3[O]rarrKlO_(3)),(Hence","),(bar(2KMnO_(4)+Kl+H_(2)Orarr2KOH+2MnO_(2)+KlO_(3))):}`
