Cojugate Acids and Bases

How do you determine conjugate acids and conjugate bases from a regular acid and base?

You add an H+ ion to a base to make a conjugate acid, and remove an H+ ion from an acid to make a conjugate base.

The conjugate acids and bases are just the products of a acid base reaction. If you wrote the reverse reaction the conjugate base would just be the base. It's not like an base can only be a base or conjugate base.

In a chemical equation, the acid and the base on the reactant side would be known as the "regular" acid and base while the acid and the base on the product side would be known as the conjugate acid and conjugate base. Also they are related in a way that professor Lavelle called "the conjugate seesaw," in which the stronger the acid/base, the weaker its conjugate base/acid. Hope this helps!

A base with a hydrogen ion attached to it is a conjugate acid. An acid with a hydrogen ion taken away from it is a conjugate base.

Here's an example:
HCl + NaOH --> NaCl +H2O
In this reaction, HCl is the acid and NaOH is the base. Since the HCl donates a proton it is the acid and since the OH- accepts the proton it is the base. NaCl would be the conjugate base and would be a acid-conjugate base pair with HCl. H2O would be the conjugate acid and would be a base-conjugate acid pair with H2O. Hope it helps!

Can someone clarify what a conjugate acid or conjugate base is exactly?

A conjugate ion is the molecule/ion formed when a proton is added to a base.

A conjugate base is what remains of an acid molecule/ion when a proton is lost.


Example:

HCl + NH3 --> NH4+ + Cl-
Here, NH4+ is the conjugate acid, and Cl- is the conjugate base.

The one with the hydrogen ion is the acid and the one without is the base

the acid and bases on the reactant side, when it goes into the product side, the base that accepts the H+ becomes the conjugate acid while the acid that loses H+ becomes conjugate base.

The conjugate acid and conjugate base are only used when talking about a molecule in reference to another. A conjugate acid of something will have one more H than the thing it's a conjugate of. A conjugate base will have one less H than the the thing it's a conjugate of.
