Flame Test- Sodium Chloride -
The flame test is preformed by burning a metal salt using a flammable liquid. Each chemical (in this case metal ion) gives off a characteristic color (seen here as changes in colors of the flames) when the electrons fall back down from their excited state and emit light at certain wavelengths (colors).

Finally, calcium chloride burned a starburst orange color but the internet says it burns a brick red color. 3 The unknown metallic salt was sun orange, just like Sr(NO3)2, which means these were the same compounds. Conclusion-In the lab, each compound was
Burning Salts - Sciencetheatre
We get to see this effect by burning the metal salts in ethanol, and can see as each salt gives out a different color. This effect is something that you may have already known, but never thought about. The majority of paints get their colors simply by adding a dye
[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.
