A) \[C{{r}^{2+}}\]
B) \[MnO_{4}^{-}\]
C) \[MnO_{4}^{3-}\]
D) \[C{{u}^{+}}\]
Correct Answer: B
Solution :
[b] In \[MnO_{4}^{2-}\] manganese is in + 6 oxidation state which is having highest stability. \[MnO_{4}^{2-}\] disproportionates in neutral or acidic solution. \[3MnO_{4}^{2-}+4{{H}^{+}}\xrightarrow{{}}2MnO_{4}^{2-}~+Mn{{O}_{2}}+2{{H}_{2}}O\]You need to login to perform this action.
