Acids, Bases, and Salts · Semester 2

Qualitative Analysis: Cations

Students will use chemical tests to identify unknown cations.

Key Questions

  1. Explain the chemical basis for the observations in cation tests (e.g., precipitate formation, color changes).
  2. Systematically eliminate possibilities when identifying an unknown cation.
  3. Analyze the results of flame tests to identify specific metal ions.
