How to Calculate pH from Ka in Weak Acids

In this tutorial video I show you step by step how to calculate the pH of a weak acid when given the acid dissociation constant, Ka. We apply this is two separate example practice problems. I also discuss the concept of polyprotic acids in this video.

Chemistry lectures and "How to" videos from a university professor and Ph.D. chemist. I also live stream every week on Twitch where I discuss the latest news in climate change, space travel, and the intersection of science and politics.
