Chapter 10: Acids, Bases, and Salts
Acids, bases, and salts are fundamental concepts in chemistry, essential for understanding a wide range of chemical reactions and processes. This chapter introduces students to the properties, theories, and applications of these compounds, providing a comprehensive understanding of their behavior in different contexts.
Key Topics Covered:
- Introduction to Acids and Bases
- Historical background and definitions.
- Natural occurrences and everyday examples.
- Theories of Acids and Bases
- Arrhenius Theory: Acids produce H⁺ ions, and bases produce OH⁻ ions in aqueous solutions.
- Bronsted-Lowry Theory: Acids are proton donors, and bases are proton acceptors.
- Lewis Theory: Acids are electron pair acceptors, and bases are electron pair donors.
- Properties of Acids and Bases
- Physical and chemical properties.
- Strong and weak acids/bases.
- Concept of pH and pOH.
- Indicators and their uses in determining acidity and basicity.
- Salts
- Definition and formation of salts.
- Types of salts: normal, acidic, and basic salts.
- Properties and uses of salts.
- Common examples and their applications in daily life.
- Neutralization Reactions
