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 Reactions in Acidic Solutions**
**Exercise:** Balance the following half-reaction in an acidic solution.
\[ \text{CrO}_3 \rightarrow \text{Cr}^{2+} \]
To balance this half-reaction, follow these general steps:
1. **Identify and Balance the Atoms**: Balance all elements in the equation except hydrogen and oxygen.
2. **Balance Oxygen**: Add water molecules to the side deficient in oxygen.
3. **Balance Hydrogen**: Add hydrogen ions (H⁺) to the side deficient in hydrogen.
4. **Balance Charge**: Add electrons (e⁻) to the more positive side to balance the electrical charge.
Apply these steps to the half-reaction provided to achieve a balanced equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb73fd08b-4071-4726-b0d1-d357287a66bd%2Feb2a921c-7de4-4e64-9e37-ff4cde43bbf1%2Facrtiq_processed.jpeg&w=3840&q=75)
