Eleven white solids—they all look alike! How can they be identified?
Students are challenged as they follow a qualitative analysis flow chart to determine the identity of the eleven unknowns—all common household substances. Following the flow chart, students use a variety of physical and chemical procedures to test the unknowns and record descriptive observations on the data sheet. Students ultimately make a “guess” as to the identity of the unknowns.
Teacher Notes and reproducible student handouts include easy-to-follow lab instructions, a detailed flow chart, and data tables. Eleven unknown samples, test reagents, 11 polypropylene jars, test tubes, pipets, and wood stirrers are provided.
Super Value Kit is complete for 5 classes of 30 students working in pairs.
