Titrate metal ions found in tap water using the reagent ethylenediaminetetraacetic acid (EDTA). The end point is found using a dye called Eriochrome Black T (EBT), which also forms complexes with metal ions in solution. Students learn how to properly use pipets and burets and will perform stoichiometric calculations involving volume and molarity.
Kit includes reproducible student procedure, complete Teacher Notes with sample data and answers to questions, and all necessary chemicals.
Complete for 24 students working in pairs.
