How can you determine the conjugate acid of a strong base and the conjugate base of a strong acid in a reaction?

Generally, the conjugate acid or base will just be the product other than H3O+ or OH-. For example, in the equation NH4+ + H2O <-> NH3 + H3O+ NH4+ is the acid with NH3 as its conjugate base.

The conjugate acid to the base will be the molecule that has gained a proton. The conjugate base to an acid will be the molecule that loses a proton.
HCOOH + H2O----HCOO[-] + H3O+
HCOOH is the acid and HCOO[-] is the conjugate base.

The conjugate parts are usually the products. In order to identify the conjugates in the products, you need to know if the reactants are acids or base. In terms of that, you should see whether the reactants accept or donate protons. Acids generally lose protons, therefore, having conjugate base in the product; base, however, generally accepts protns, and have conjugate acids in the product.

Write out the reaction. Once you write it out you'll find that you end up with most likely 2 products one of which is your conjugate base or conjugate acid and the other is H30+ or OH-.
