what chemical turns fire blue

Best answer

That is why bothcopper chloride and copper sulfateburn blue. Other metallic salts produce some outstanding colors but can be hard to obtain. Salts of strontium and lithium burn red, while barium compounds burn green. Purples can be obtained by burning combinations of strontium (red) and copper (blue) compounds.

Why do flames turn blue? When you see a flame, you are seeing something that is glowing with a certain color. Heat naturally causes things to glow. If you heat up a piece of iron hot enough, it will glow red. Heat it more and it glows orange or yellow. The temperature controls the color.

Other metallic salts that will change the color of a fire include potassium chloride or potassium permanganate (Condy鈥檚 Crystals), which burn violet, magnesium sulfate (epsom salts), which burns white. and copper chloride or copper sulfate which burn blue. Calcium salts burn orange. Salts are made up of a metal and a nonmetal.

These gases are all alkanes and are gas with a blue flame. There are copper compounds that burn with a blue flame including Copper (I) chloride, commonly called cuprous chloride (CuCl), Copper carbonate (CuCO 3 ), Copper arsenite (CuHAsO 3) and Copper sulfate CuSO 4. LPG 鈥?propane 鈥?and natural gas (methane gas) both burn with a blue flame color.

The stench alerts us to gas leaks that might otherwise be undiscovered. Methane does burn with a blue flame color, when there is complete combustion, with a methane gas flame temperature of approximately 1,960C.
