Unit 8.1 starts our lesson on acid base chemistry and equilibrium. While this lesson does not directly correspond to any of the AP Chemistry curriculum it is integral to understanding all the other sub-units! |

In 8.2 we covered the classification of acids or bases as either strong or weak. The VAST majority of acids/bases are weak electrolytes and thus are weak acids/base. For this course there are only 6 strong acids to know, and only two strong bases. Watch the lecture to find out more. |
After the brief lectures of 8.1 and 8.2, which cover mostly definitions and basics, unit 8.3 is a bit of a marathon. We went over pH, utilizing Ka or Kb, and percent dissociation. Get comfortable because this lesson is a doozy! |

Hydrolysis simply translates to water breaking. In this lesson we learn that salts actually cause a solution to be either acid or basic. After this lesson we took our unit 8 quiz which had us:
|
Acid-Base reactions typically are utilized in a titration, a chemical procedure where one is introduced to the other. Titration curves are created when this process is done VERY slowly. In lab we will conduct multiple titrations, where we look only at the equivalency point. However you do need to know and understand the curves. |

The final lesson of unit 8 is a deep dive into buffers and the use of the henderson hasselbalch equation -- which personally I don't use XD Long story short, see how I solve buffer equations, and prepare for the second to last test! |
After this lesson you'll need to complete the personal progress check for Unit 8. This will be a quiz grade, so do your best. Earning a score that is highlighted in yellow will earn you a 3/5, light green will net you a 4/5, but get that coveted green and you'll get earn a 5/5
