Lab Tests, Results, and Sulfuric Acid
You may want to change the title of this chemistry PowerPoint to "Identifying Compounds in the Laboratory." Individual slides explain tests that can be performed to confirm what element you have: carbon dioxide, carbonates, and metal...
Beyond Benign
Electron Transitions
Ready for a lab with a lot of razzle-dazzle? Young chemists observe flame tests of common salts through an always-popular activity. The updated resource focuses on observation skills, collaboration, and green chemistry practices.

The Three E's - Exciting Energetic Electrons
Students perform flame tests on salts and record the electron configurations for various cations. They analyze and record the results using spectroscopes.
Curated OER
Chemical Sleuthing
Students engage in a lesson which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra produced.
