MICROLab – Vinegar Titration on Paper

In this inquiry lab, students use a paper microfluidic device to measure the acetic acid content of vinegar.    By Marya Lieberman, Kimberley Frederick, Vincent Remcho, and Renee Cole Description:  The titrator consists of 13 paper squares separated by hydrophobic wax barriers;  the back of the titrator is also hydrophobic.  Each square is loaded with…

Gravimetric Acid-Base Titration

This analysis is designed to replicate the classic acid-base determination of an unknown titration, but using household chemicals as the standard, titrant, indicator, and unknown. Notably this analysis employs a digital scale and syringes in the place of pipettes and burettes, making this a unique gravimetric approach to acid base titrations.
