The number of moles of `KMnO_(4)` reduced by `1 "mol of" KI` in alkaline medium is

A

one fifth

B

five

C

one

D

two

Text Solution

Verified by Experts

The correct Answer is:
C
In alkaline medium , `KMnO)(4)` is reduced to `K_(2)MnO_(4)`
`KI+H_(2)OtoKOH+HI`
`2Koverset(+7)MnO_(4)+2KOHto2K_(2)overset(+6)MnO_(4)+H_(2)O+[O]`
Hence , one mole of `KMnO_(4)` is reduced by one mole of KI.
