Strontium burns with a bright red color in a flame test.
The flame of strontium chloride is a bright red color.
The flame of strontium nitrate is red. It produces a bright red color when ignited.
Strontium chloride burns with a red flame due to the presence of strontium ions in the compound. The strontium ions emit red light when they are excited during the combustion process.
Strontium nitrate emits a bright red flame when it is burned.
Strontium chloride (SrCl) burns with a bright red flame. This characteristic color is due to the presence of strontium ions, which emit red light when heated. The vivid red flame is often used in pyrotechnics and fireworks to create striking visual effects.
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.
A better question would be "which elements burn red", as more than one element burns red. Lithium chloride burns red, calcium chloride burnds a red-orange, and strontium chloride burns bright red.
strong red (crimson)
The flame color of magnesium sulfate is typically a pale white or colorless flame when it is burned. This color is due to the presence of magnesium in the compound, which burns with a relatively faint flame color compared to other metals.
A lazy yellow flame is the "coolest" flame.
