Product Details

How do we analyze an unknown chemical? Making comparisons to “known” chemicals is one common method. In this laboratory activity, students will perform qualitative ion tests on four known anion and six known cation solutions. Then, students will then be challenged to use their observations to analyze and identify the cation and anion that make up an unknown salt, through comparison to the known tests. Reproducible student handouts include easy-to-follow lab instructions, data tables and questions. Helpful Teacher Notes provide preparation information, tips, sample data and answers to questions. Ion testing solutions, test reagents, pipets, labels and wood stirrers are provided.

Super Value Kit is complete for 5 classes of 30 students working in pairs. Fifteen reusable 24-well reaction plates are recommended and available separately. Perform this experiment in a fume hood or well-ventilated lab.
