In flame tests salts that are dissolved in water are evaporated using a hot flame. In the flame the metal atoms become excited and produce their characteristic spectrum of light. However, since the observer does not use a spectroscope only one color is observed.
How does the color of the flame produced by calcium …
Calcium flame is orange. It’s not as intense as sodium, but much more intense than potassium. Calcium is used as a colorant for orange firework stars, but they are fairly uncommon. One of the idiosyncrasies I’ve observed is that calcium orange sta

Each flame needs time to get extremely hot to yield the maximum emission from the metal. On the camera, this sodium burning looks kind of pink, but in real life, it was quite yellow. Since you have plenty of sodium chloride at home, you can check this one out live, but make sure you have a controlled environment for containing the flame.

Flame Test - Weebly
Most salts contain a metal and a non-metal. Look at the compounds we tested and explain how we can be sure that it is the metal atoms that are responsible for the colors that you see. Based on the data from the test, I cannot conclude that the metals caused the change in color.
Classroom Resources | Flame Test (Rainbow Demo) | AACT
Use flame tests to identify a metal or metallic salt by the color that it produces when it is put into a flame. Calculate the frequency of light given its wavelength. Calculate the wavelength of light given its frequency. Identify an unknown metal by the color it emits
FLAME TEST AND ATOMIC SPECTRA LAB
By comparing the color given off by an unknown with the known metal salts, the identity of the metal salt can be determined. Flame Tests Activity (As an option, this could be a demo rather than a student activity) Materials: Bunsen burner Wooden splints (9
Expt 2 Calcium by visible spectroscopy
Average amount of calcium in diet: 100–250 mg/24-hour sample High amount of calcium in diet: 250–300 mg/24-hour sample Ultraviolet/visible (UV/vis) absorption spectroscopy is a technique that can be used to determine low levels of calcium. Because

Cool Fire - Rice University
It should be noted that sodium is present as an impurity in many if not most metal salts. Because sodium imparts an especially intense color to a flame, flashes of the sodium may be observed in nearly all solutions tested. Scientific Concepts: When an element is
Determination of Total Calcium and Magnesium Ion Concentration
The dye–metal ion complex is less stable than the EDTA–metal ion complex. For the titration, the sample solution containing the calcium and magnesium ions is reacted with an excess of EDTA. The indior is added and remains blue as all the Ca2+ and Mg2+
Flame Photometers - Sedico Ltd.
Flame Photometers including THE AFP-100 Automatic Flame Photometer Flame photometry is an atomic emission method for the routine detection of metal salts, principally Na, K, Li and Ca. Quantitative analysis of these species is performed by measuring the
Flame tests | Creative Chemistry
Different salts contain different metal ions (charged particles). When solutions of these salts are heated in a Bunsen burner flame, they give off characteristic colours. For example, sodium ions make the flame turn yellow, the same colour made by sodium street lamps.
Calcium Metal | AMERICAN ELEMENTS
Calcium is a reactive, soft metal that is a meer of the alkaline earth elements. It frequently serves as an alloying agent for other metals like aluminum and beryllium industrial materials like cement and mortar are composed of calcium compounds like calcium carbonate .

Color of chemicals - Wikipedia
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths .
