A) 6
B) 5
C) 4
D) 2
Correct Answer: B
Solution :
\[\underline{\begin{align} & \underline{\begin{align} & MnO_{4}^{-}+8{{H}^{+}}+5{{e}^{-}}\xrightarrow{{}}M{{n}^{2+}}+4{{H}_{2}}O \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,[F{{e}^{2+}}\xrightarrow{{}}F{{e}^{3+}}+{{e}^{-}}]\,5\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \\ \end{align}} \\ & MnO_{4}^{-}+8{{H}^{+}}+5F{{e}^{2+}}\to M{{n}^{2+}}+5F{{e}^{3+}}+4{{H}_{2}}O \\ \end{align}}\] \[\therefore \]Five electrons gets transferred.You need to login to perform this action.
