Among the following pairs of ions the lower oxidation state in aqueous solution is more stable than the other in

Options

A. `TI^(+), TI^(3+)`
B. `Cu^(+), Cu^(2+)`
C. `Cr^(2+), Cr^(3+)`
D. `V^(2+), VO^(2+)`

Answer

A

Explanation

`TI^(+)` ions are more stable than `TI^(3+)` and the `TI^(3+)` ions change to `TI^(+)` ions thereby acting as oxidis agents.
