Conjugate acids and bases
Conjugate acid
The substance that is formed when a base takes on a proton.
Conjugate base
The substance that remains after the acid has given up a proton.
The acid on the left side of the equation becomes the conjugate base on the right. The base on the left becomes the conjugate acid on the right. Conjugates must always differ by one hydrogen ion.
Examples:
1. H2O and H3O+ are a conjugate base pair. They differ by one H+.
2. If HSO4- is the acid, the conjugate base SO4^2-. Take out the H+ and you are left with SO4^2-.
3. If HBr is the acid, the conjugate base is Br-. Take away the H+ from the acid.
