A pink flame is often caused by the presence of potassium salts in a burning substance. When potassium is heated, it emits a pink or purple color in the flame. This can be seen in certain fireworks, where potassium compounds are used to create colorful effects.
Helium does not burn in a flame test because it is an inert gas and does not react with the flame to produce a characteristic color.
Lithium flame colours are red or crimson when burned in a flame. This is due to the presence of lithium ions emitting light at specific wavelengths as they are heated in the flame. The colour can vary slightly depending on the temperature of the flame and other factors.
A pink firework is usually achieved by using strontium compounds in the composition. Strontium salts produce a pink color when they ignite and burn. By incorporating these compounds into the firework formula, it creates the desired pink hue when the firework explodes in the sky.
A flame bends toward the wind because the flow of air carries the heat and combustion products away, creating an area of lower pressure on the windward side of the flame. This pressure difference causes the flame to lean in the direction of the wind.
A flame roll out can be caused by a disruption in the airflow or fuel mixture within a gas appliance. This can lead to the flame being pushed out of the combustion chamber instead of burning inside it. Common causes include blocked vents or flues, improper installation, or a malfunctioning gas valve. It is important to address flame roll out promptly as it can pose a safety hazard due to the risk of fire or carbon monoxide poisoning.

A pink color from the spectral lines of lithium.
Selenium nitrate typically gives a pink or reddish flame color when subjected to a flame test.
The chemical that causes pink burns on the skin is hydrofluoric acid.
Lithium hydroxide (LiOH) produces a lilac or pink flame test when burned.
Helium does not burn in a flame test because it is an inert gas and does not react with the flame to produce a characteristic color.
Flame luminosity occurs because of lack of oxygen. Also, the air holes in the Bunsen burner affects the flame.
Lithium flame colours are red or crimson when burned in a flame. This is due to the presence of lithium ions emitting light at specific wavelengths as they are heated in the flame. The colour can vary slightly depending on the temperature of the flame and other factors.
