`PbO_(2)` can act as an oxidising agent.

Explanation

To understand how \( \text{PbO}_2 \) can act as an oxidizing agent, we can break down the explanation into several steps:

### Step 1: Understanding Oxidizing Agents
An oxidizing agent is a substance that can accept electrons from another substance during a chemical reaction. This process results in the oxidation of the other substance while the oxidizing agent itself gets reduced.

### Step 2: Identifying the Composition of \( \text{PbO}_2 \)
\( \text{PbO}_2 \) is lead(IV) oxide, which consists of lead (Pb) and oxygen (O). In this compound, lead is in the +4 oxidation state.
