Qualitative Chemical Analysis
EXPLORE a standard scheme of qualitative chemical analysis.
DISCOVER the presence or absence of a limited number of common positive ions in an “unknown” solution.
ENRICH inorganic chemistry.
This title is available only as software.

- Aluminum (III): Al3+
- Barium (II): Ba2+
- Calcium (II): Ca2+
- Chromium (III): Cr3+
- Copper (II): Cu2+
- Iron (II): Fe2+
