Study Notes
Arrhenius Acid-Base Theory
- HCl is an Arrhenius acid as it dissociates in water to produce H⁺ ions.
- The Arrhenius theory is limited to aqueous solutions only.
- NH₃ (ammonia) is classified as an Arrhenius base.
- Strong acids, according to the Arrhenius theory, are acids that fully dissociate in water.
- These strong acids completely dissociate in water, producing hydrogen ions.
Limitations of Arrhenius Theory
- The theory does not account for the behavior of acids and bases in non-aqueous solvents.
- It does not consider the role of conjugate acid-base pairs in chemical reactions.
Note: The statement about the Arrhenius theory being more common than any other theory is not included as it is not a key fact about the theory itself, but rather a comparative statement.
