The salt in the air from the sea, turns a camp fire flame blue as it is lit, it then retearns to normal.
this gas is called nitrogen.
A Bunsen burner flame turns blue when it is adjusted to have the right amount of air mixture. This blue color is due to complete combustion of gas with sufficient oxygen, resulting in a hotter and more efficient flame.
The hottest part is where the flame is light blue or blue; which gradually turns to yellow as the flame is cooled by the colder outer air. When the safety flame (yellow) is on, the hottest point is the tip of this flame.
Imagine a sparkler... Cobalt Chloride sends off millions of tiny, yellow sparks that shoot upward with the flame. Do not get to close when doing a flame test
To get a blue flame, you typically need to burn a fuel source that produces complete combustion, such as natural gas or propane. This results in a more efficient and cleaner burn, creating a blue flame due to the high temperature and oxygen supply. Adjusting the air-to-fuel ratio and ensuring proper ventilation can also help achieve a blue flame.
this may show it works.
Lithium turns red in flame tests.
To get a blue flame with a Bunsen burner, ensure the air intake is fully open by turning the collar at the base of the burner counterclockwise to allow more oxygen into the mixture. Adjust the gas flow to achieve a blue, well-defined flame with minimal yellow tip. If the flame is too yellow, increase the air intake until it turns blue.
A flame turns blue when it achieves complete combustion, meaning there is enough oxygen present for the fuel to burn efficiently. The blue color is due to the presence of carbon dioxide and water molecules in the flame, which emit a blue light as they undergo chemical reactions.
Blue flame. because it does not have carbon
The blue flame is caused by allowing more air into the stem of the Bunsen burner - it produces a fiercer, hotter flame. If the air flow is restricted, the flame turns yellowish and is more like a wax candle.
