Answer 1

Hey there!

Your Question =>
The compound $AgF_2$ is an unstable compound. However, if formed, the compound acts as a very strong oxidizing agent. Why?

Answer:

The oxidation state of Ag in
$AgF_2$ is +2. But, +2 is an unstable oxidation state of Ag.

Therefore, whenever $AgF_2$ is formed, silver readily accepts an electron to form Ag+. This helps to bring the oxidation state of Ag down from +2 to a more stable state of +1. As a result,

$AgF_2$ acts as a very strong oxidizing agent.

Answer 2

concept :- Ag⁺ is more stable than Ag²⁺ Cation because of the presence of completely filled configuration of Ag⁺ .
and we know, an oxidizing agent has great tendency of accepting electrons.

now, In AgF2 , Ag is in +2 oxidation state . it is highly unstable so, it readily accepts an electrons to attain +1 oxidation state which is more stable.
e.g., Ag²⁺ + e --------> Ag⁺

that's why AgF2 acts as strong .oxidizing agents .
