Ammonium Salts and Solutions
The importance of ammonium salt solutions is covered in a video that explains how to solve the reactions, the chemical equations, and the structure of the various ions.

Heterogeneous Equilibrium
When performing a gas lab, we are often under pressure. A four-video set offers a brief explanation of Henry's law and demonstrates a lab. The last two videos prompt learners to complete brief quizzes over the material.

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]
