Write chemical reactions to justify that hydrogen peroxide can function as an oxidising as well as reducing agent.

Explanation

To demonstrate that hydrogen peroxide (H₂O₂) can act as both an oxidizing agent and a reducing agent, we can write down specific chemical reactions for each case.

### Step 1: Hydrogen Peroxide as an Oxidizing Agent

**Reaction 1:**
When hydrogen peroxide reacts with iron(II) ions in an acidic medium, it oxidizes Fe²⁺ to Fe³⁺.
