Well, this has to do because of a hydrolysis reaction. And let's see what happens so this is a weak acid and that means its Ka will be low. So equilibrium for this guy will lie all the way to the left, not the right as in this case. That means at our solution, when our solution is formed, equilibrium, we're going to have some of these guys present, right? We're going to have a bunch of these guys present. And that means at equilibrium, we're not only going to have water and salt, we're also going to have this guy present.
