AP Chemistry Acid Base Equilibrium: Working with the Acid Dissociation Constant Ka

This video is focused on the acid dissociation constant Ka. This includes how to set up a Ka expression, calculating Ka from pH and calculating pH from Ka. More importantly, a bunch of examples are done to make sure that by the end of the video, you have a pretty solid understanding of the math involving Ka. At the very end, I briefly discuss the concept of polyprotic acids and how such acids relate to Ka.
