Standard reducation potential at 25^(@)C...

Standard reducation potential at `25^(@)C` of `Li^(+)//Li`, `Ba^(2+)//Ba, Na^(+)//Na` and `Mg^(+)//Mg` are `-3.05, -2.90, -2.71` and `-2.37` volt respectively. Which one of the following is the strongest oxidising agent ?

A

`Mg^(2+)`

B

`Ba^(2+)`

C

`Na^(+)`

D

`Li^(+)`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) A cation having maximum (positive) value of standard reduction potential is the strongest oxidising agent. Hence, `Mg^(2+)` is the strongest oxidising agent.
