In this lecture we're going to talk a bit more about titrations and equivalence points. Now, earlier in another video, we saw that we can actually calculate our equivalence point using a formula. Now, if you want to learn more about that, check out the link above. Now, actually calculating your equivalence point isn't very useful when you're conducting your experiment. When you're titrating, you want to actually visualize the equivalence point. And to visualize it, you use two things.
