How can you tell the difference between chemical compounds, when so many of them are white and powdery? The fifth installment in a series of ten videos exposes learners to flame tests and formation of insoluble compounds as methods of identifying metal ions in solution. In addition, the resource highlights differences in testing between transition and non-transition metals.

Instructional Ideas
- Show the video prior to performing flame tests in the lab
Classroom Considerations
- Pupils should have prior knowledge of types of reactions, chemical nomenclature, and the periodic table
- Try enabling subtitles if you plan for the class to take notes
Pros
- The demonstrations show interesting color changes and can easily be performed as a lab by students themselves
- Chemical formulas are given during the tests to further promote reaction concepts
Cons
- Transition metals used in some portions of the video are incorrectly named using western Arabic, rather than Roman, numerals
