Which of the following is an incorrect statement ? (a)In a redox reaction in acidic medium, KMnO4 produces Mn2+ ions. (b)In a redox reaction in strongly alkaline medium, KMnO4produces MnO ions. (c)In a redox reaction in neutral medium, KMnO4 produces MnO2. (d)In a redox reaction in alkaline medium, KMnO4 produces Mn2O7. Ans. (d) Sol. In alkaline medium 2KMnO + 2KOH 2K MnO + H O + [O] MnO + e MnO -> -> can be reduced to MnO if reducing agent its present K MnO + H O MnO + 2KOH + [O] -> OR MnO + 2H O +2e MnO + 4OH -> MnO C O NO SO
