Flame Tests of Metal ions - Santa Monica College
Analysis: For each metal ion tested, obtain the wavelength of light corresponding to the observed flame color from the table below. Note that the wavelengths supplied here are in nanometers. Using these wavelengths, calculate the frequency and energy of
[Demo] Colored Flames - light | Coursera
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 Tests - University of North Florida
Place a candle securely in the metal pie pan, and pour some water in the pan. Light the candle, remeering flame safety. Use the tongs or pliers to hold a toothpick so the soaked end is in the candle’s flame. Observe the color, and record data in the table
Flame Test Lab - Ryan''s Digital Portfolio
6) What metal was found in your unknowns (based on your observations)? The metals ended up being Calcium Chloride and Borax, we guessed borax, but didn''t have detailed enough notes to identify that the first one was Calcium Chloride. 7) Do you think we
Q & A: Flame test: ion or anion? | Department of …
If you use a pure metal powder and observe a color spectrum, it is clearly due to the metal atoms as there is nothing else. The question that you are asking comes into play when you use a metallic salt, which upon heating disassociates into metal ions and nonmetalic anion atoms or groups.
FLAME TEST AND ATOMIC SPECTRA LAB
For example, sodium makes the flame turn bright yellow – this is the same yellow color made by sodium street lamps and many fireworks. Materials: Bunsen burner Wooden splints (9 per group) Solutions (1.0 mol/L) of the following metal salts lithium chloride
Metal ion Colour Aluminium, Al 3+ White - dissolves in excess sodium hydroxide solution Calcium, Ca 2+ White - no change in excess sodium hydroxide solution
Flame Test Lab Activity - University of South Florida
1. Perform a flame test to identify the characteristic color of metal ions. 2. Identify the metal ion in an unknown solution. 3. Calculate the energy of emitted photons. Materials: (per lab group) 10 ml dilute solutions of the following: Barium Chloride
Dip the hot wire into a little solid sodium chloride contained in a test tube, and hold the wire in the flame. 6. Using the procedures from Steps 2 and 3, test 3 mL samples of nitrates of barium, calcium, strontium, lithium, potassium, and copper.
Flame Test Lab - Rachel Edwards'' Digital portfolio
The flame color was blue/orange. The unknown compounds were one of the ones we had tested previously. From my observations I thought unknown #1 was calcium chloride and unknown #2 was borax. It had turned out I was correct in my observations
Lab: Flame Tests "At Home"
For example both sodium chloride and calcium chloride are colorless crystals and as a fine powder they are white. In order to identify which salt you have, you have to do a test on the material. A traditional method for identifying elements in compounds is called a flame test.
Flame Tests - Drs.Cavanaugh
Flame Tests Just as a fingerprint is unique to each person, the color of light emitted after excitation of an element is different for each element. When a metallic element’s electrons absorb energy, by heating for example, the electron is said to become “excited”.
Do It Yourself | Causes of Color
You can test sodium carbonate and calcium carbonate to prove to yourself that it is the metallic part (the ion) of the compound producing the color. Hence, sodium carbonate will produce a yellow flame and calcium carbonate (chalk or limestone) will produce a red-orange flame.
