Current Question (ID: 8569)

Question:

$\text{The compound AgF}_2 \text{ (unstable) acts as a/an:}$

Options:

1. $\text{Oxidising agent.}$
2. $\text{Reducing agent.}$
3. $\text{Both oxidising and reducing agent.}$
4. $\text{Neither oxidising and reducing agent.}$

Solution:

$\text{Hint: Ag is unstable in +2 form.}$ $\text{EXPLANATION:}$ $\text{The oxidation state of Ag in AgF}_2 \text{ is +2. But, +2 is an unstable oxidation state of Ag.}$ $\text{Therefore, whenever AgF}_2 \text{ is formed, silver readily accepts an electron to form Ag}^+\text{.}$ $\text{This helps to bring the oxidation state of Ag down from +2 to a more stable state of +1.}$ $\text{As a result, AgF}_2 \text{ acts as a very strong oxidizing agent.}$ $\text{Since AgF}_2 \text{ readily accepts electrons (gets reduced from +2 to +1), it causes other substances to lose electrons (get oxidized), making it an oxidizing agent.}$
