Absolutely, let's break down oxidation-reduction (redox) reactions and provide examples to illustrate
them:
**Oxidation-Reduction (Redox) Reactions Simplified:**
1. **What Are Redox Reactions:** Redox reactions are chemical reactions where electrons move
from one substance to another. These reactions involve the transfer of electrons.
2. **Everyday Examples:** Redox reactions are all around us. For instance, when iron rusts, hair is
bleached, or batteries generate electricity, these involve redox reactions.
3. **Not Always Oxygen:** While many redox reactions involve oxygen (like when things burn), they
don't always need oxygen. It's about the transfer of electrons, not just oxygen. Let's take an
example:
- **Sodium and Oxygen:** When sodium reacts with oxygen, it forms sodium oxide:
4Na (s) + O₂ (g) → 2Na₂O (s)
