Most products we use every day, including food, beverages, medication and cleaning solutions, have acidic and basic properties! The amount or concentration of acid or base in a sample may be determined by acid–base titration.
In this advanced-inquiry lab, students conduct a series of acid–base titrations and determine the concentrations of two unknowns. The lab begins with an introductory activity in which students qualitatively analyze an acid and base using pH paper. This activity provides a model for a guided-inquiry experiment, during which students collect quantitative titration data using a buret and pH meter. Each group uses two acids and two bases. One of the acids will have a known molarity and the other will have an unknown molarity. The same applies to the two bases. Students will graph titration curves from the collected data and determine the concentration of each unknown. A variety of acids and bases, strong and weak, are provided for the class to perform different combinations of titrations.
FLINNprep is just one of the powerful learning pathways accessed via PAVO, Flinn’s award-winning gateway to standards-aligned digital science content paired with hands-on learning.
Complete for 24 students working in pairs. A version of this lab is available as a Wet/Dry Advanced Inquiry Laboratory Kit for One Period (Catalog No. AP8945).
