3. Balance the following redox equation using the half-reaction method. Remember a substance may be both oxidized and reduced simultaneously. Br2 > BrO31- + Br1- (base/alkaline)
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.

![### Balancing Redox Equations Using the Half-Reaction Method
#### Example 3:
Balance the following redox equation using the half-reaction method.
*Remember, a substance may be both oxidized and reduced simultaneously.*
**Unbalanced Equation:**
\[ \text{Br}_2 \longrightarrow \text{BrO}_3^{1-} + \text{Br}^{1-} \quad \text{(base/alkaline)} \]
---
To balance this redox equation:
1. **Identify the oxidation states of Br in the reactants and products.**
2. **Write the oxidation half-reaction and the reduction half-reaction.**
3. **Balance the atoms other than oxygen and hydrogen.**
4. **Balance the oxygen atoms by adding \( \text{H}_2\text{O} \).**
5. **Balance the hydrogen atoms by adding \( \text{OH}^- \) (since the reaction is in a base/alkaline environment).**
6. **Balance the charges by adding electrons.**
7. **Combine the half-reactions by ensuring that the electrons are canceled out.**
8. **Verify that the final equation is balanced both for mass and charge.**
This balanced equation will help you understand the principles of redox reactions in an alkaline environment.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa0d27a45-2e15-4eee-ac6b-80b9e19010e1%2Fec1e34d2-cc4d-445d-b5a7-4272fbde5c80%2F5wp2dlw_processed.jpeg&w=3840&q=75)
