And Ha will react in water to produce hydronium and a conjugate base. Now, we've spoken about something called Ka, or the acid ionization concept. If you don't know what K is, check out the link above. But Ka is basically the product of the concentrations of the product. So the concentration of this guy times the concentration of this guy divided by the concentration of the reaction of this guy. And we said that if our Ka value is high, if it's bigger than one, that means our acid is a strong acid.
