In alkaline medium, \(I^{-}\)is oxidised to ' X ' by \(\mathrm{KMnO}_4\). The oxidation state of iodine in ' X ' is:
- A 7
- B 0
- C 5
- D 3
Answer & Solution
Correct Answer
(C) 5
Step-by-step Solution
Detailed explanation
In alkaline medium, the reaction between permanganate ion and iodide ion is given by the balanced chemical equation: 2MnO\(_{4}^{-}\) + I\(^{-}\) + H\(_{2}\)O \(\rightarrow\) 2MnO\(_{2}\) + IO\(_{3}^{-}\) + 2OH\(^{-}\) The product 'X' formed by the oxidation of I\(^{-}\) is the…
