Manganese \((VI)\) has ability to disproportionate in acidic solution. The difference in oxidation states of two ions it forms in acidic solution is \(...... .\)
- A \(3\)
- B \(2\)
- C \(1\)
- D \(4\)
Answer & Solution
Correct Answer
(A) \(3\)
Step-by-step Solution
Detailed explanation
\(MnO _{4}^{2-}\) disproportionates in a neutral or acidic solution to give \(MnO _{4}^{-}\)and \(Mn ^{+4}\) \(3 MnO _{4}^{2-}+3 H ^{+} \longrightarrow 2 MnO _{4}^{-}+ MnO _{2}+2 H _{2} O\) O.S. of \(Mn\) in \(MnO _{4}^{-}=+7\) O.S. of \(Mn\) in \(MnO _{2}=+4\)…
