Lab Activity 5: Bright Light Spectrum of Various Gases

Objective:

To identify unknown samples of gas. In this lab you will design your own procedures to successfully accomplish the goal of determining the characteristic band pattern emitted by a certain gas when electrically excited. Using this data, you will then reference the table below to positively match the unknown sample with the known samples below.

Materials needed:

Spectrometer, Various unknown samples of gas lights.
