Creating a solubility chart
This is not an inquiry lab (and it is based on an experiment in Essential Experiments for Chemistry)
While it was flipped to become one when I used in Chem 11 (see "will a double-replacement reaction occur?"), I wanted my 12s to get to the point and generate a solubility chart. I provided a chart for data collection, as well as a full procedure. C/E/R is used in the lab conclusion

Finding the Ksp of lead(II) iodide
This experiment is based on Lab 12C in Essential Experiments for Chemistry. In the original format, I found that students got lost in the picky instructions and missed the bigger concepts. Often, they could get the correct answer without having any idea where it came from or what it meant.

Competing Equilibria - Demo
This demo (which I got from Sheila Ross) is a gem! Students are asked to predict which precipitates will form based on the size of each Ksp. A few surprises along the way require Le Chatelier's principle.

Chloride ion titration
I want students to learn proper titration procedure, so this lab was definitely not inquiry-based.
I used Essential Experiments for Chemistry for my procedure.
