What is the relationship between oxidation and oxidising agent in a redox reaction? Write an example of a redox reaction showing the relationship between oxidation and the oxidising agent.

Explanation

### Step-by-Step Solution

1. **Understanding Redox Reactions**:
- A redox (reduction-oxidation) reaction involves the transfer of electrons between two species. In these reactions, one species is oxidized (loses electrons) while the other is reduced (gains electrons).

2. **Defining Oxidation**:
- Oxidation is defined as the process where a substance loses electrons. This results in an increase in the oxidation state of that substance.
