We can graph PH versus, say, temperature, right? And this will create a very good graph. That's exactly why we use PH in the PH scale, just simply because it's a convenient way of converting inconvenient Molar numbers to convenient numbers. Okay? Now, one last note about this is that our range for PH can range anywhere from zero to 14, where zero is the smallest possible PH and 14 is the largest possible PH. So let's look at this size.
