Keep going! Check out the next lesson and practice what you’re learning: www.khanacademy.org/science/ap-chemistry-beta/x2ee… A buffer has an effective pH range of one pH unit on either side of the pKₐ value for the weak acid. If the pH of a buffer goes out of this range, the buffer will no longer be effective at resisting large changes in pH.
