How do you classify Bronsted acids and bases?

Answer 1

Bronsted acids and bases are classified by their ability to donate or accept a proton.
An acid is a proton donor, and a base is a proton acceptor .

A Bronsted-Lowry acid, very similar to an Arrhenius acid, is a compound that donates an #H^+# to another substance.

The other substance need not be water; that is the only distinction.

Thus, in theory, the Arrhenius model can still be used to categorize the acids.

In the Brønsted-Lowry model, the other substance (such as ammonia, alcohol, or anything else) need not be restricted to water.

The Arrhenius and Bronsted-Lowry definitions diverge on the base side.

An Arrhenius base refers specifically to the hydroxide #OH^-)# ion, while a Bronsted-Lowry base refers to any atom or ion capable of accepting or bonding to a proton.

Consider nitric acid and ammonia as an example.

#HNO_3 + NH_3 -> N H_4^+ + NO_3^-#
Nitric acid donates an #H^+# to #NH_3#.

Observe that in the Arrhenius model, the proton is taken up by the water.

When ammonia picks up the #H^+#, it acts as a proton-acceptor.
#NH_3# is the Bronsted-Lowry base in this example.
Notice there is no reference to #OH^-#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
