The compound `AgF_(2)` is unstable compound. However, if formed, the compound acts as a very strong oxidising agent. Why ?

Explanation

In `AgF_(2)`, silver exists as `Ag^(2+)` which quickly undergoes reduction to form `Ag^(+)`. So it acts as strong oxidizing agent
`underset(("unstable"))(Ag^(2+)) + e^(-) rarr underset(("stable"))(Ag^(+))`
