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