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.

![### Displacement Reactions Involving Metals
This document is a table designed to record observations from displacement reactions involving various metals. The table includes columns for recording observations before and after mixing, and for classifying the reactions. Below is a transcription of the table content:
| Reaction | Observations (Before mixing) | Observations (After mixing) | Classify Reaction (Select all that apply) |
|-----------------------------|------------------------------|-----------------------------|------------------------------------------|
| Zn(s) + H₂SO₄(aq) | | | 0 Items |
| Mg(s) + HCl(aq) | | | 0 Items |
| Zn(s) + CuSO₄(aq) | | | 0 Items |
At the bottom of the table, there are links to additional resources:
- **Solubility Table**
- **Activity Series**
### Instructions for Use:
1. **Reaction Column**: This column lists the chemical reactions involving metals, expressed in chemical notation. Examples include:
- Zinc reacting with sulfuric acid: Zn(s) + H₂SO₄(aq)
- Magnesium reacting with hydrochloric acid: Mg(s) + HCl(aq)
- Zinc reacting with copper(II) sulfate: Zn(s) + CuSO₄(aq)
2. **Observations (Before mixing)**: In this column, note any initial observations before the chemicals are mixed. This might include the physical state, color, or any noticeable features of the reactants.
3. **Observations (After mixing)**: Record any changes or reactions that take place upon mixing the substances. Look for color changes, gas evolution, temperature change, precipitation, or other notable reactions.
4. **Classify Reaction**: This column is for categorizing the type of reaction that occurs after mixing the substances. Based on the observed outcomes, select the appropriate classifications.
### Graph/Diagram Explanation:
There are no specific graphs or diagrams included in this table; it primarily serves as an observation sheet for students to fill out during laboratory experiments involving displacement reactions of metals.
### Educational Notes:
- **Displacement Reactions**: A type of chemical reaction where an element reacts with a compound and takes the place of another element within the compound.
- **Observation Skills**: Developing a keen eye for detail in observing physical and chemical changes during reactions is crucial for understanding chemical processes.
