Strontium and Flame Colors
The color imparted to a Bunsen flame by strontium salts is primarily due to the electronic transitions of the strontium ions when they are heated.
Understanding Flame Tests
- Flame tests are qualitative analysis techniques used to identify the presence of certain metal ions based on the characteristic colors they emit when heated.
- When strontium salts, such as strontium chloride (SrCl2) or strontium nitrate (Sr(NO3)2), are introduced into a Bunsen flame, the heat excites the electrons in the strontium ions.
Color Emission
- As the excited electrons return to their ground state, they release energy in the form of light.
- Strontium specifically emits light in the red region of the spectrum, producing a distinct and recognizable color.
Characteristics of the Flame Color
- The flame produced is often described as "crimson red" or "brick red," which is a deep red hue that easily distinguishes it from other metal ions.
- This property is useful in various applications, including pyrotechnics and analytical chemistry, where identifying the presence of strontium is crucial.
Conclusion
- Thus, the correct answer to the question regarding the color imparted to the Bunsen flame by strontium salt is option 'D' - "crimson red." This vivid color is a result of the unique interaction between strontium ions and heat, making strontium a notable element in flame tests.

A flame test is performed by introducing a sample into the blue flame of a bunsen burner and noting any change in the colour of the flame. The tests can be used to detect the presence of some metallic elements in salts. With strontium salt, the colour of Bunsen flame ranges from crimson to red.
