Flame Test Lab

Introduction

The Flame Test Lab is one of the most widely performed 1st year high school chemistry labs. Bohr's model of how atom's absorb energy is being utilized in this lab.

Atoms of metals are investigated to "see" what colors are emitted from each metal atom when the atoms are exposed to a infinite number of different energy packets
(Planck's explanation of energy). The metal atoms are not in the elementary form but as ions in solution. This change of form does not effect the atom's ability to absorb
energy.

The actual objective of the lab is to determine the unknown "atom" (actually a solution) from a set of known "atoms".

Procedures

You task is to determine the color (using the 7 colors or a combination of these, so NO CELERY or MAUVE ) emitted from the atom when exposed to a flame (i.e. energy).

You will record ( in your data table) the first color you see. It may require more than one sampling. If you exposed the sample to the flame long enough all solution will become bright orange in color.

Make sure that the wire loop does not touch the benchtop, it should be place with the loop portion on a piece of paper provided in the station.


Questions/problems: There will be a separate question/problem sheet.
