This page contains links for a student in a general chemistry course. This type of course is a more in-depth study of Chemistry and usually requires a previous chemistry course. If you are in your first chemistry course, you may want to look over at the Introductory Chemistry page.

Videos

I have an entire sequence of videos available for a second semester general chemistry course. The Chapters here are correlated to OpenStax Chemistry 1st edition, but the subject material will work with whatever textbook you use (I don’t do much directly from textbooks!). Note that if you watch just a single video here, I do some odd things like pause in funny positions after asking a question. These videos are meant to be used with a system such as PlayPosit that will pause and actually ask you those questions. So when you see me do that, I encourage you to pause the video and actually try to answer the question.

• Using the small x assumption and ICE tables to calculate equilibrium concentrations
• Finding the pH of a weak acid (before a titration)
• Finding the pH of a weak acid titrated with a strong base, before the equivalence point (in the buffer region)
• Finding the pH of a weak acid titrated with a strong base, at the equivalence point
• Calculating the voltage in a concentration cell
