At a PH of seven, the charge will be zero. Okay? So at a PH of seven, what will be the charge on this group here? Well, because the PKA is eight and it's above seven, our guess, that means this will have a positive charge, right? Remember, this will only lose an H atom and become neutral at this PH or above. And because we're below, because our guess has a PH of seven, this will be a positive charge.
