Identify the oxidising agent (oxidant) in the following reactions
`Pb_(3)O_(4) +8HCl to 3PbCl_(2) +Cl_(2) +4H_(2)O`

Explanation

To identify the oxidizing agent in the given reaction, we will analyze the changes in oxidation states of the elements involved. The reaction provided is:

\[ \text{Pb}_3\text{O}_4 + 8\text{HCl} \rightarrow 3\text{PbCl}_2 + \text{Cl}_2 + 4\text{H}_2\text{O} \]

### Step 1: Identify the oxidation states of each element in the reactants and products.

- In \( \text{Pb}_3\text{O}_4 \):
- Lead (Pb) has an oxidation state of +4 (since it is combined with oxygen).
