This lab is a great introduction to qualitative analysis.
- Activities Include Identifying Common Metallic and Non-Metallic Ions in Zinc and Cadmium
- Students Research Distinctive Properties in Tested Substances
- Kit Contains Tests for Known and Unknown Substances
- Safe and Clear Test Results
Specific positive and negative ions are often used to identify inorganic substances. In this kit, students 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, and colorful.
Ordering information: This lab includes chemplates with spatulas and gas collector caps, Lab-Aids, gas delivery tubes, absorbent paper, calcium carbonate, unknowns, barium chloride, antimony chloride, cadmium nitrate, lead acetate, potassium permanganate, sodium sulfate, sodium sulfite, zinc nitrate, hydrochloric acid, limewater, and sodium sulfide.
