Product Details

Eleven white solids—they all look alike! How can they be identified? Students 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.
