The flame test for strontium - a strong red color.
Strontium will produce different colours dependant on the circumstances. If the flame has oxygen and hydrogen present, the flame will be red. With chlorine in the flame it will be a brighter red. If it is the strontium atoms excited by themselves they produce a violet colour.
Red. Strontium is often used in fireworks to give off a deep red colour when burned.
Strontium gives a crimson color in a flame test due to the excitation of its electrons. When strontium ions are heated, the energy from the flame excites the electrons to higher energy levels. As these electrons return to their ground state, they release energy in the form of light, which for strontium corresponds to a characteristic wavelength in the red part of the spectrum, resulting in a crimson color.
There are several possibilities. Strontium is probably the most beautiful red, but many of its salts are hygroscopic.
