Acids and bases (A-level only) study guide

Study Guide: Acids and Bases

1. Definitions and Concepts

• Brønsted-Lowry Theory: Familiarize yourself with the definitions of acids and bases according to this theory.
• Conjugate Pairs: Practice identifying conjugate acid-base pairs in various reactions.

2. Proton Transfer Reactions

• Write and balance equations for proton transfer reactions. Understand the role of water as a solvent in these reactions.

3. Strength vs. Concentration

• Distinguish between the strength of an acid and its concentration. Use examples to illustrate your understanding.

4. pH Calculations

• Master the calculations of pH and [H⁺] using logarithmic relationships. Practice problems involving Kw and its application.

5. Weak Acids and Ka

• Learn to construct Ka expressions for weak acids and calculate pH using given concentrations and Ka values. Understand the concept of pKa and its relationship to Ka.

6. Titration Techniques

• Review the process of acid-base titrations, including how to analyze titration curves and determine endpoint indicators.

7. Buffer Solutions

• Understand how buffers work, including the calculations for pH in acidic and basic buffers. Explore real-life applications of buffers in biological systems.

8. Practical Applications

• Engage in practical experiments to observe pH changes during titrations and the effectiveness of buffers. Record and analyze your findings.
