### Conjugate acids vs conjugate base

I understand how to identify a conjugate acid vs. conjugate base, but I do not understand how to give a formula for conjugate acid or conjugate base? example(below)

Conjugate acid is the original formula plus a hydrogen ion. Conjugate base is minus a hydrogen ion.

I don't think this has been covered in lecture yet. Has it? So don't worry about now knowing how to do that rn.

It has not been covered in lecture quite yet, but it will be on the final!

### Re: Conjugate acids vs conjugate base

an acid ionizes to make H+ and its conjugate base while a base combines w/ H+ to make its conjugate acid. basically the conjugate base you subtract one proton, so HSO4^- would become SO4^-2. for the conjugate acid you add one proton, so HSO4^- would become H2SO4.

### Re: Conjugate acids vs conjugate base

To find the conjugate base, you remove a proton, which would give you SO4-. To find the conjugate acid, you add a proton, which would give you H2SO4. Hope that helps!

### Re: Conjugate acids vs conjugate base

conjugate acid has an added hydrogen ion

### Re: Conjugate acids vs conjugate base

Basically, the conjugate acid includes the attachment of a proton to the base, and the conjugate base involves the removal of a proton from the acid. In this case, the conjugate base will be SO4^2- and the conjugate acid is H2SO4!

The conjugate base of a Bronsted-Lowry acid is the species formed after an acid donates a proton.
The conjugate acid of a Bronsted-Lowry base is the species formed after a base accepts a proton.

### Re: Conjugate acids vs conjugate base

So the acid gives a proton and the base accepts it, so the conjugate base of an acid would lose an H+ ion, and the conjugate acid of a base would gain an H+ ion?

### Re: Conjugate acids vs conjugate base

The conjugate acid has an addition H+ while the conjugate base takes away an H+

### Re: Conjugate acids vs conjugate base

For your conjugate acid you take the original formula and add a hydrogen. You take a hydrogen out of it to find your conjugate base.

### Re: Conjugate acids vs conjugate base

Acid-base conjugate pairs differ by just one H+ ion and always occur together

For example, in the following scenarios:

A) NH3 + H2O ---> NH4+ + OH-

The conjugate base is OH-

and the conjugate acid is NH4+

Similarly in

B) HCl + H20 ---> Cl- + H3O+

The conjugate base is Cl-

and the conjugate acid is H3O+

Hope this helps :)
