A) \[4/5\]
B) \[3/5\]
C) 1
D) \[2/5\]
Correct Answer: D
Solution :
The balance chemical equation is: \[2MnO_{4}^{-}+6{{H}^{+}}\,\,+\,\,\,5SO_{3}^{-\,-}\,\xrightarrow{{}}\] \[2M{{n}^{++}}+\,\,5SO{{_{4}^{-}}^{-}}+\,\,3{{H}_{2}}O\] From the equation it is clear that Moles of \[MnO_{4}^{-}\] required to oxidise 5 moles of \[SO_{^{3}}^{-\,-}\] are 2 Moles of \[MnO_{4}^{-}\] required to oxidise 1 mole of \[SO_{3}^{-\,-}\] are \[2/5\].You need to login to perform this action.
