Detection of Ions in Solutions Using Acid/Base Chemistry: A Quality Control Test

This curriculum unit from Cornell Science Inquiry Partnerships aims to teach students about acid/base chemistry through the use of titration. Students act as quality control testers to determine the amount of Ca2+ in Tang® and Mg(OH)2 in milk of magnesia by standardizing three solutions for ion detection. This experiment was designed for use by high school chemistry classes, either Regents or AP, and is in most lab settings.
