|
The Arrhenius definition has many limitations
|
Many species act as bases without containing OH ions
(such as ammonia, NH3). |
|
a more general definition of acids and bases was developed byJohannes Brønsted and Thomas Lowry (1923):
|
Definition #2: Brønsted – Lowry
Acids – proton donor Bases – proton acceptor A “proton” is really just a hydrogen atom that has lost it’s electron! |
|
A Brønsted–Lowry acid…
…must have a removable (acidic) proton.a removable (acidic) proton. A Brønsted–Lowry base… …must have a pair of nonbonding electrons. NH3, H2O |
a removable (acidic) proton.
a removable (acidic) proton. |
|
The Brønsted definition means NH3 is a -------- in water — and water is itself an ACID
