And so we produce a negative charge here and a positive charge here. And this is basically equivalent to this equation here, where the H is this H here and the A is this entire molecule here and the Ha is this molecule here. But for this particular reaction the PKA is equal to 9.7. Now what 9.7 means is it's a relatively large value, it's relatively positive. And so, this isn't a very good acid. But if the PH is driven high enough, it will become a good acid in a sense that it will readily dissociate and give off that H atom.
