Right, but how will it increase? Well, let's look at the graph of PH versus volume added, where PH is the Y axis, and volume added of our base in this case is the x axis. So according to this graph, we see that the relationship is based on a sigmoidal curve. And what that means is that initially, when you first add some known amount of concentration of base, the PH change will be very little. The PH won't change by that much. And in fact, from this much to this much volume added, the PH only rises by maybe 0.5.
