Identification of Substances

SCIENTIFIC CONCEPTS/PROCESSES

  • A thorough introduction to acids and bases
  • Produce hydrogen by reacting acids with metals
  • Collect and safely test hydrogen
  • Produce carbon dioxide by reacting carbonates with acids
  • Collect and test carbon dioxide
  • Observe effects of acids and bases on indicator dyes
  • Measure concentration of acids by titration of an “unknown”
  • Perform a neutralization experiment

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 found in:

  • zinc
  • antimony
  • sulfate
  • sulfite
  • cadmium
  • barium
  • sulfide
  • carbonate

Through this identification process, they 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!
