This lab uses a burette, an acid of known concentration, a base of unknown concentration, and phenolphthalein to teach about the principles and practice of titration neutralization reactions.
This lab is an excellent way to introduce or enhance your lessons on titration and the equation MaVa=MbVb. It's also a great exercise in precision and laboratory technique.
My labs are straightforward. Some of them are paper labs, but the ones that involve significant laboratory setup or calculations to be made on the part of the teacher are written about in a Teacher Notes section at the end of those particular labs. I use relatively safe and inexpensive chemicals. Of course, safety precautions are always noted at the beginning of the lab.
