Study Notes
Arrhenius Theory
- Defines acids as substances that produce H+ ions in water
- Defines bases as substances that produce OH- ions in water
- Simple and easy to understand
- Focuses on aqueous solutions
- Limitations: Only applies to water-based solutions, cannot explain substances like ammonia (NH3)
Brønsted-Lowry Theory
- Defines acids as proton (H+) donors
- Defines bases as proton (H+) acceptors
- Works in both aqueous and non-aqueous systems
- Explains the behavior of bases like NH3
- Limitations: Focuses only on proton transfer, does not explain reactions involving non-protonic acids and bases (e.g., BF3)
Lewis Theory
- Defines acids as electron pair acceptors
- Defines bases as electron pair donors
- The broadest definition, including all acid-base reactions
- Explains reactions where no protons are involved
- Limitations: More abstract and less intuitive, does not prioritize H+ ions
