Flame colorants
| Color | Chemical |
|---|---|
| Red | Strontium chloride or strontium nitrate |
| Orange | Calcium chloride |
| Yellow-green | Barium chloride |
| Orange-yellow | Sodium chloride (table salt) |
Why does strontium produce a red flame?
The electrons “jump” from their ground state to a higher energy level. The color emitted by larger atoms is lower in energy than the light emitted by smaller atoms. So, for example, strontium (atomic number 38) produces a reddish color, while sodium (atomic number 11) produces a yellowish color.
What color flame is strontium sulfate?
Pyrotechnic colorant
| Color | Compound name | Chemical formula |
|---|---|---|
| Red | Strontium oxalate | SrC2O4 |
| Red | Strontium sulfate | SrSO4 |
| Red | Strontium chloride | SrCl2 |
| Orange | Calcium carbonate | CaCO3 |
What color does strontium produce?
reds
Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender.
Why do different elements give off different colors of light in a flame test?
When an electron drops from one level to a lower energy level, it emits a quantum of energy. The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.

What is the color of strontium?
yellowish
Freshly cut strontium has a silvery appearance, but rapidly turns a yellowish color with the formation of the oxide. The finely divided metal ignites spontaneously in air. Volatile strontium salts impart a beautiful crimson color to flames, and these salts are used in pyrotechnics and in the production of flares.
Which of the following cation gives red Colour in the flame test?
strontium cations
Red colour is obtained from strontium cations. > Calcium compound gives brick red color in flame test.
