Base in Earth Science
In Earth Science, a base is a substance that can neutralize an acid and has a pH value greater than 7. Bases are also known as alkalis and are the opposite of acids. They are often found in household products such as soaps, cleaning agents, and certain food items. In geological terms, bases can also refer to minerals with a high pH value, such as limestone and marble.
Properties of Bases:
Common Bases:
- Sodium hydroxide (NaOH)
- Calcium hydroxide (Ca(OH)2)
- Ammonia (NH3)
- Potassium hydroxide (KOH)
Uses of Bases:
Bases have various uses in different industries and everyday life:
- Manufacturing of soaps and detergents
- Neutralizing acidic soils in agriculture
- Water treatment processes
- Food production and processing
Study Guide Questions:
- What is the pH range of a base?
- Provide examples of common bases and their uses.
- Explain the difference between a base and an acid.
- How do bases neutralize acids?
Understanding the properties and uses of bases is important in Earth Science as it helps in comprehending the interactions between different substances in the environment and their impact on natural systems.
