Potassium chlorate

Potassium chlorate is a chemical compound with the formula KClO₃. In its pure form, 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 plays an important role in making safety matches. This means it helps matches burn safely and reliably when struck.

Production

Potassium chlorate is made in factories by mixing sodium chlorate with potassium chloride. This creates potassium chlorate, which does not dissolve well in water, so it 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 create the same product.

Uses

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

In science labs, potassium chlorate can be heated to create oxygen gas, which can be collected for experiments. It can also be used in special demonstrations 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. However, 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 very quickly and sometimes even catch fire or explode when mixed with many materials that can burn. It burns strongly when combined with almost any burnable material, including things that are usually only a little flammable, like dust or lint. When potassium chlorate is mixed with certain fuels and then comes into contact with 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.
