Potassium chlorate

Potassium chlorate is a chemical compound with the formula KClO₃. It looks like a white solid. It is the second most common chlorate used in industry after sodium chlorate. Because it is a strong oxidizing agent, it helps make safety matches that burn safely when struck.

Production

Potassium chlorate is made in factories by mixing sodium chlorate with potassium chloride. This makes potassium chlorate, which does not dissolve well in water and settles out of the mixture. Sodium chlorate is made by running electricity through a solution of sodium chloride, which is regular table salt.

Sometimes, potassium chlorate is also made by running electricity through a solution of potassium chloride. In this process, chlorine gas forms and reacts with potassium hydroxide to make the same product.

Uses

Potassium chlorate was used in early firearms and percussion caps. It is also an ingredient in smoke compositions, like those in smoke grenades.

In science labs, potassium chlorate can be heated to make oxygen gas for experiments. It can also be used in special shows where it reacts with sugary candies to create a fun visual effect.

Potassium chlorate has some uses in farming, such as helping certain trees produce fruit in warmer places. But it is important to handle this chemical carefully because it can be very reactive and dangerous when mixed with certain materials.

Safety

Potassium chlorate is a very strong oxidizing agent. It can react quickly and sometimes catch fire or explode when mixed with materials that can burn. It burns strongly when combined with almost any burnable material, including dust or lint. When mixed with certain fuels and sulfuric acid, it can catch fire. Some mixtures of potassium chlorate with substances like lactose, sulfur, antimony(III) sulfide, or phosphorus can be very sensitive to shock or friction.
