Now, in the same way that we talk about ionization constants of water, we can also talk about ionization constants of acids. Except now they're not Kw, they're ka, where A is for our acid. So let's suppose we have a hypothetical acid Ha reacting with a water molecule in a liquid state. Now, what will happen? Well, this acid will donate the H, releasing the H, while the base will accept that age, creating a hydronium ion and a conjugate base. So this is our conjugate acid, our conjugate base and our conjugate base and our conjugate acid.
