The ion(s) that act/s as oxidizing agent in solution is/areA. `Tl^(+)` and `Al^(3+)`B. `B^(3+)` and `Al^(3+)`C. `Tl^(3+)` onlyD. `B^(3+)` only

Answer» Correct Answer - C
`Tl^(+)` ions are more stable than `Tl^(3+)` ions and thus, `Tl^(3+)` ions change to `Tl^(+)` ion thereby acting as oxidising agent.
`underset("(Less stable oxidising agent)")(Tl^(3)" Compounds ")+2e^(-) rarr Tl^(+)underset(("(More stable"),("reducing agent)"))("Compounds")`
