QUESTION

# What are conjugate acid-base pairs?

All acids have a conjugate base. All bases have a conjugate acid. Acids "donate" H^(+) when they react. This is most easily seen when they dissociate in water:

H_2SO_4 + H_2O => HSO_4^- + H_3O^+

In this example, sulfuric acid (H_2SO_4) is an acid because it "donates" H^+ to the water. It becomes the hydrogen sulfite ion (HSO_4^-) which is the conjugate base of sulfuric acid.

The same idea applies to a base:

NH_3 + H_2O <=> NH_4^+ + OH^-

Ammonia (NH_3) is a base because is "accepts H^+ from water to come its conjugate acid, the ammonium ion (NH_4^+).
