Question

The compound $Ag{F}_2$ is an unstable compound. However, if formed, the compound acts as a very strong oxidizing agent. Why?

Answer 1

The oxidation state of Ag in $Ag{F}_2$ is +2. But, +2 is an unstable oxidation state of Ag. Therefore, whenever $Ag{F}_2$ is formed, silver readily accepts an electron to form $A{g}^{+}$. This helps to bring the oxidation state of Ag down from +2 to a more stable state of +1. As a result, $Ag{F}_2$ acts as a very strong oxidizing agent.
