A) one fifth
B) five
C) one
D) two
Correct Answer: D
Solution :
In alkaline solution, \[KMn{{O}_{4}}\] is reduced to \[Mn{{O}_{2}}\](colourless). \[2KMn{{O}_{4}}+2{{H}_{2}}O\xrightarrow{{}}Mn{{O}_{2}}+2KOH+3[O]\] \[KI+3[O]\xrightarrow{{}}KI{{O}_{3}}\] Hence, two moles of \[KMn{{O}_{4}}\] are reduced by one mole of\[KI\].You need to login to perform this action.
