Specific positive and negative ions are often used to identify inorganic substances. In this kit, students are asked to identify common metallic and non-metallic ions in zinc, cadmium, antimony, barium, sulfate, sulfide, sulfite, and carbonate. Through the identification process, students learn that each substance has distinctive properties. As a closing activity, students conduct chemical tests on four unknown substances.

All test results are safe, clear, colorful, and unmistakable! Since one kit provides supplies for twelve students working individually, LAB-AIDS® recommends ordering additional kits. The Identification of Substances Kit is an excellent complement to both the Qualitative Analysis Chromatography Kit (LAB-AIDS® No. 18) and the Identification of Chemical Reactions Kit (LAB-AIDS® No. 84).
