Chemistry of Fireworks

By Khalifa Alzaabi

Over the decade’s fireworks have been a source of happiness and amazement in different cultures around the world. But what produces their dazzling array of effects? This post will explain briefly about the reaction that happens when launching an air cracker.

Chemicals and colors

The chemistry that is involved in the fireworks is considered to be very essential since it can change the color of the fire. Each compound produces its own color and each color has its own energy and wavelength. Depending on the mixture that is available in the firework, it will produce that specific color. For example, the mixture that creates blue includes varying amounts of copper chloride compounds, while red comes from strontium and lithium salts. Moreover, just like dyes, secondary colors are made by mixing the ingredients of their primary-color relatives. A mixture of copper (blue) and strontium (red) makes purple and so over.
