When exposed to flame, each salt metal produces waves of specific colors. For example, sodium produces yellow, strontium produces red, and barium produces green. Mixing the chemicals can produce a wide variety of hues, including purple made from a mixture of strontium and copper components.

How are the colors of fireworks produced from the energy levels of electrons in atoms?

When magnesium (Mg) or aluminum (Al) particles are burned, they produce incandescent white sparks, as if it were a camera flash. The iron (Fe) or charcoal particles, if they do not reach very high temperatures, radiate a golden color.

How are firework lights produced?

Sulfur flows over potassium nitrate and carbon, which are then burned. This combustion reaction quickly produces a large amount of energy and gas, in other words, an explosion. If there is a small hole for the gas to escape, the reaction launches the fireworks into the air.

What substances are used in pyrotechnics to form the color orange?

Calcium salts.

Known as: calcium carbonate, calcium chloride, and calcium sulfate. These salts are responsible for giving the orange color. Sodium salts such as: sodium nitrate, sodium oxalate and cryolite. With these salts we can create the yellow color.

What color does potassium produce in fireworks?

Specifically, strontium salts are added to the black powder and potassium perchlorate that make the firework “explode” for a deep crimson red glow.

To achieve this, there are a variety of substances that alter the original shape of the explosion and make it look much more colorful, such as the following:

Green: Barium salts (Ba) Red: Strontium salts (Sr) Orange: Calcium salts (Ca) Blue: Copper salts (Cu) White: magnesium and titanium.

How do you make colored fire?
