Khan Academy: Introduction to Buffers
An introduction to buffer systems, which regulate pH in blood. [6:20]
Khan Academy
Khan Academy: Buffers, the Acid Rain Slayer
Define buffers and their compositions, and learn about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. See an experiment using indicators to showcase just how awesome buffers are. [10:51]
Khan Academy
Khan Academy: Common Ion Effect and Buffers
See an example of calculating the pH of solution that is 1.00 M acetic acid and 1.00 M sodium acetate using ICE table. Also shown is another example of calculating pH of a solution that is 0.15 M ammonia and 0.35 M ammonium nitrate. [13:19]
Khan Academy
Khan Academy: Buffer Solution P H Calculations
See examples of calculating the pH of a buffer solution using the Henderson-Hasselbalch equation, including the pH of the buffer solution after adding some NaOH. [11:38]

Khan Academy: P H and P Ka Relationship for Buffers
How the Henderson-Hasselbalch equation can be used to look at the ratio of conjugate acid and base using relationship between buffer pH and pKa. [7:50]
Khan Academy
Khan Academy: Buffer Capacity
Learn the definition of buffer capacity, and see an example showing why it depends on the absolute concentrations of the conjugate acid and base. [10:44]

Khan Academy: Ways to Get a Buffer Solution
This tutorial describes the two main situations where you get a buffer: making a buffer for a specific pH by combining a weak acid and a salt containing the conjugate base, and using a neutralization reaction by combining a weak acid and...

Khan Academy: Buffers, the Acid Rain Slayer
In this episode created of Crash Course, Hank talks about how nutty our world is via Buffers! He defines buffers and their compositions, talks about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. Plus, a...
Khan Academy
Khan Academy: Buffers and Henderson Hasselbalch
A buffer solution contains a mixture of a weak acid and its conjugate base (or a weak base and its conjugate acid). The equilibrium between the weak acid and its conjugate base allows the solution to resist changes to pH when small...
