Azide facts for kids
Azide is a special kind of ion that contains three nitrogen atoms linked together. Its chemical formula is N3-. An ion is an atom or molecule that has an electric charge because it has either gained or lost electrons. Azide has a negative charge.
Azides are formed from a substance called hydrazoic acid. The most well-known azide is sodium azide. Many azides can be very toxic, meaning they are poisonous, and some can even be explosive.

What is an Azide?
An azide is a chemical compound that contains the azide ion (N3-). This ion is made up of three nitrogen atoms. These atoms are arranged in a straight line. The azide ion has a negative charge, which makes it react with other substances.
How Azides are Made
Azides are often made from hydrazoic acid. This acid is a liquid that is very explosive and poisonous. When hydrazoic acid loses a hydrogen atom, it forms the azide ion. This process is called deprotonation.
Properties of Azides
Azides have some interesting and important properties. They are known for being strong reducing agents. This means they can give electrons to other substances in a chemical reaction.
Safety with Azides
It is very important to be careful with azides. Many of them are highly toxic, which means they can be dangerous if swallowed or if they touch your skin. Some azides are also explosive. This means they can react very quickly and release a lot of energy, causing an explosion. Because of these dangers, azides are usually handled only by trained scientists in special labs.
Uses of Azides
Even though azides can be dangerous, they have some important uses.
Airbags
One of the most common uses for an azide is in car airbags. Sodium azide is used in the system that inflates airbags during a car crash. When a car crashes, a small electrical signal causes the sodium azide to break down very quickly. This reaction produces a lot of nitrogen gas. The gas fills the airbag in a fraction of a second, protecting the people inside the car.
Other Uses
Azides are also used in some chemical reactions in laboratories. They can be used to make other chemical compounds. Scientists also study azides to learn more about how different chemicals react.
