color of flame of metal salts calcium in korea

PC\|MAC

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.
