Consider the following list of regents: Acidified `K_(2)Cr_(2)O_(7)`, alkaline `KMnO_(4)`, `CuSO_(4)`, `H_(2)O_(2)`, `CI_(2)`, `O_(3)`, `HNO_(3)`, and `Na_(2)S_(2)O_(3)`. The total number of reagents that can oxidis aqueous `I^(Theta)` ion `I_(2)` is

Text Solution

Verified by Experts

The correct Answer is:
7
Any oxidising agent will oxidise `1^(Theta)` to `I_(2)`. These oxidising agent are
1. `K_(2)Cr_(2)O_(7)//H^(o+)` 2. `KMnO_(4)//OH^(Theta)`
3. `CuSO_(4)` 4. `H_(2)O_(2)`
5. `CI_(2)` (Reduction potential of `CI_(2) gt I_(2)`)
6. `O_(3)` 7. `HNO_(3)`
