Titration of an Esterification Reaction to Determine Equilibrium Constant

This activity was submitted for a 2016 ChemEd X Call for Contributions soliciting input regarding the big ideas being put forth by organizations like AP. The author shares a lab activity that relies on connections - between stoichiometry, esterification, equilibrium, kinetics, titrations and uncertainty of calculations. He also shares the resources he created.

Deciding the appropriate number of significant figures for the reporting of numerical data is not an obvious or easy task.
