Title: Quantization of Energy
Objective(s): Determine the composition of a new star.
Hypothesis:
Make a prediction for how to identify an unknown element and the chemical composition
of a star.
For Part I, create an explanation to describe the relationship between the identity of an
element and the color of light it produces when it is heated.
For Part II, create an explanation to describe the relationship between the composition
of an unknown substance and its emission spectrum (line spectrum).
Procedure:
List the procedures of the lab in a clear, concise, and appropriate detail.
Clean a platinum wire before each trial by dipping it into the test tube of hydrochloric
acid and then heating the wire in the hottest part of the Bunsen burner flame until no
color shows.
Select a known solution from the given test tubes, and dip the clean platinum wire into
the solution.
Hold the wire in the hottest part of the Bunsen burner flame and observe the color
produced in the flame. Record the observed color in your data table.
Use the spectroscope to observe the color of flame for each of the given elements. You
should be able to see the individual lines making up light emitted from the heated
gases.
Record the colors and wavelengths values of the elements emission line in your data
table.
Use the spectroscope to observe the light emitted from a star. Record the color and
wavelength values of the brightest lines in the spectrum.
Variables:
Identify the controlled, independent, and dependent variable of both parts of the lab
