Which one is a strong oxidizing agent? A) Mn⁴⁺ B) Mn³⁺ C) Mn⁷⁺ D) All of the above

Explanation

An oxidizing agent readily accepts electrons, and higher oxidation states of a metal generally indicate a greater tendency to gain electrons and act as an oxidizing agent. 

Mn⁴⁺:

While not as strong as MnO4-, Mn4+ is still a potent oxidizing agent due to its high oxidation state. 

Mn³⁺:

This ion is considered a particularly strong oxidizing agent because it readily reduces to Mn²+, a more stable configuration. 

Mn⁷⁺:

In the form of permanganate ion (MnO₄⁻), Mn⁷+ is the strongest oxidizing agent among the listed options.

It has the highest oxidation state of manganese and readily accepts electrons.
