Conjugate acids

How do you determine which is a conjugate acid and conjugate base?

[Sydni Bednarek 3I]

A conjugate acid is an acid that is produced by the reaction of a base and water. After a base is protonated, it can act as an acid, hence the term conjugate acid. A conjugate base is a base that is produced by the reaction of an acid and water. After an acid is deprotonated, it can act as a base, hence the term conjugate base.

Adding on to that, the Bronsted-Lowry states that conjugate acid-base pairs are usually seen as two different molecules that have a difference in protons. So, when a proton is added to a base, it makes it a conjugate acid and when this proton is removed from an acid, it is then a conjugate base. I hope this helps!

On top of that, we can tell if the product will be a conjugate acid or conjugate base based on the reactants. If the reactants are an acid and water, then the products will be H30+ and a conjugate base. The water picked up a H+ ion from the acid, making it a conjugate base since it lost a H+ ion in the reaction.
