QAIPMT-2005-Ch-2481: NEET 2005 Chemistry - Class 12 AIPMT-2005-Ch-2481 Solution: The number of moles of \(KMnO_4\) reduced by one mole of KI in…
The number of moles of reduced by one mole of KI in alkaline medium is
Multiple Choice Options
- A one
- B two
- C five
- D one fifth
Step-by-Step Verified Solution
The chemical reactions involved in this case are
as follows :
KI + H 2 O _ KOH + HI
2KMnO 4 + 2KOH _ 2K 2 MnO 4 + H 2 O + [O]
Thus, for overall reaction, two moles of KMnO 4
are reduced by two moles of KOH or KI. Hence,
one mole of KI is required to reduce one mole of
KMnO 4 .
