Atomic Emission Spectroscopy (AES)
In the first part of this lab, you will observe and measure the emission lines in the visible region of the electromagnetic spectrum for hydrogen and helium, and will use the hydrogen data to investigate the Balmer-Rydberg equation.
In the second part of this experiment, you will conduct flame tests in which you will observe the emission characteristics of several elements and then identify the cations in solutions of unknown composition.
