Thurs-Day 7
Regents: we finished the gas law unit by doing a few problems (emphasizing that STP means 273 K and 1 atm - see Reference Tables) and then reviewing the kinetic-molecular theory of gases.
We then moved on to the next math of chem topic which related energy changes to physical changes/phase changes in matter. We started to draw out and explain a heating curve. We will do a cooling curve also, tomorrow.
Honors: Math of Chem 2 test today. If you did not do well, go back to your notes and learn the methods that are shown there.
AP: we covered the titration (and curve) of a strong acid by a strong base. We then did the titration curve of a polyprotic acid while emphasizing the dominant species at each significant part of the curve. We related pH to the multiple pKa's in the multiple buffer regions of the curve.
We then introduced the most challenging unit in the course: sparingly soluble salt equilibria. We need to get a big jump on that tomorrow so that you can make a dent in that unit over the weekend.
