Description
Strontium flame test. Positive result of a flame test for strontium (Sr), producing a red colour. This is due to the excitation of electrons in the strontium by the heat of the flame. As these electrons lose their energy, they emit photons of red light. The colour of the flame is different for different elements and can be used to identify unknown substances. The metal compound being tested here is strontium chloride.
