8.10 The compound AgF2 is unstable compound. However, if formed, the compound acts as a very strong oxidising agent. Why ?

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.
