Question

The standard reduction potential of `Li^(+)//Li,Ba^(2+)//Ba,Na^(+)//Na` and `Mg^(2+)//Mg`. Are -3.05,-2.73,-2.71 and -2.37 volts respectively which one of the following is strongest oxidising agent?
A. `Na^(+)`
B. `Li^(+)`
C. `Ba^(2+)`
D. `Mg^(2+)`.

Answer 1

Correct Answer - D
Strongest oxidising agent implies the most easily reduced. Higher the reduction potential, easy to reduce. Therefore `Mg^(2+)` is the strongest oxidising agent out of the given list.
