How does `Cu_(2)O` acts as both oxidant and reductant ? Explain with proper reaction showing the change of oxidation number in each example

Explanation

To understand how \( \text{Cu}_2\text{O} \) acts as both an oxidant and a reductant, we need to analyze its oxidation states and the reactions it participates in.

### Step-by-Step Solution:

1. **Determine the Oxidation State of Copper in \( \text{Cu}_2\text{O} \)**:
- The formula for \( \text{Cu}_2\text{O} \) indicates that it contains two copper (Cu) atoms and one oxygen (O) atom.
- The oxidation state of oxygen is typically -2.
- Let the oxidation state of copper be \( x \). The overall charge of the compound is neutral (0).
