In which of the following pairs of ions, the higher oxidation state in aqueous solution is more stable than the other?
I. `TI^(+), TI^(3+)` II. `Cu^(+),Cu^(2+)`
III. `Cr^(2+),Cr^(3+)` IV. `V^(2+),V^4+`

A

`TI^(+), TI^(3+)`

B

`Cu^(+), Cu^(2+)`

C

`Cr^(2+), Cr^(3+)`

D

`V^(2+), VO^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
A
`TI^(+)` ions are more stable than `TI^(3+)` and the `TI^(3+)` ions change to `TI^(+)` ions thereby acting as oxidis agents.
