Comparing the Two Theories (Leaving Cert Chemistry): Flashcards

Extends and builds upon it (doesn't replace)

Restricted to aqueous solutions only

Applies to gas reactions, non-aqueous solvents, any proton transfer

Produces $\text{OH}^-$ ions in water

Proton acceptor

Acts as base but doesn't produce $\text{OH}^-$

$\text{CO}_3^{2-}$ and $\text{HCO}_3^-$

Brønsted-Lowry theory

$\text{H}^+ + \text{H}_2\text{O} \rightarrow \text{H}_3\text{O}^+$

Substances that can act as both acids and bases depending on conditions

Brønsted-Lowry theory

No, Brønsted-Lowry extends Arrhenius
