Potassium Chlorate Structure – KCl


Preparation of Potassium Chlorate

Potassium chlorate can be produced in three ways:

1. On the industrial scale, it can be produced via the Liebig process:

Step 1. Take hot calcium hydroxide.

Step 2. Pass chlorine into it.

Step 3. địa chỉ potassium chloride.

6 Ca(OH)2 + 6 Cl2 → Ca(Cl
O3)2 + 5 Ca
Cl2 + 6 H2O

O3)2 + 2 KCl → 2 KCl
O3 + Ca

2. Potassium chlorate produced by disproportionation:

Step 1. In this method, first sodium chloride and sodium chlorate are formed by disproportionation of sodium hypochlorite.

Step 2. Then metathesis reaction takes place between potassium chlorate and potassium chloride.

3 Na
OCl(aq) → 2 Na
Cl(s) + Na

KCl(aq) + Na
O3(aq) → Na
Cl(aq) + KCl

3. Method three:

Step 1. Consider a hot solution of caustic potash.

Step 2. Pass chlorine gas into it.

3 Cl2(g) + 6 KOH(aq) → KCl
O3(aq) + 5 KCl(aq) + 3 H2O(l)

At the kết thúc of the 18th century, Potassium Chlorate was first discovered by one French chemist named, Claude Louis Berthollet. In the industry, Potassium Chlorate is considered the second most used chemical compound, while sodium chlorate is still the first one. It is essential because it can produce oxygen và that is the reason it is used both in the lab và in the chemical oxygen generators.

What is Potassium Chlorate?

Potassium Chlorate is an oxidizing agent that is very strong. It is an inorganic compound, that is represented by the chemical formula- KCl
O3. This chemical compound is also known as Fekabit or Fegabit or Kaliumchlorat. It looks lượt thích a crystalline powder and it is also called a pot crate.

It can be made easily with some household items such as the bleach và the salt substitute. It is used as chlorate in the industry and can be very toxic when it gets absorbed. It can create much irritation to lớn the human skin & eyes. It was used in making fireworks, but nowadays this use is banned in most countries.

Properties of Potassium Chlorate

The chemical formula of potassium chlorate is $mathrmKCl
O_3$and as an inorganic compound it contains one atom of potassium, one atom of chlorine, và three atoms of oxygen.

Physical properties of Potassium Chlorate

It looks like a crystalline solid at room temperature and is also crystalline và it tastes lượt thích cooling saline. The molar mass of $mathrmKCl
O_3$ is 122.55g/ml. The mật độ trùng lặp từ khóa of potassium chlorate is 2.34 g/cm3. The melting and boiling point of the $mathrmKCl
O_3$ is 400°C & 356°C, respectively.

Chemical Properties of Potassium Chlorate

A colorless compound is highly soluble in water. It is also soluble in the glycerol but shows an insoluble nature in many organic solvents. It is considered a variety of the polar solvent. In the presence of a manganese dioxide catalyst, potassium chlorate decomposes và from the reaction, it forms potassium chloride và oxygen gas.

In the presence of sulphuric acid. Potassium Chlorate reacts with sugar và this reaction releases a very large amount of energy in the form of heat, in purplish flame & it deals with the smoke.

Preparation of Potassium Chlorate

Potassium chlorate is widely used in the industry và can be made with the help of four methods and they are –

Liebig Process: When chlorine is passed into the hot calcium hydroxide và then Potassium Chloride is added to the reaction it helps lớn produce the Potassium chlorate. The equations that can represent the reaction are

$mathrm6Ca(OH)_2 + 6Cl_2: ightarrow:Ca(Cl
O_3)_2 + 5Ca
Cl_2 + 6H_2O$

O_3)_2 + 2KCl: ightarrow:2KCl
O_3 + Ca

Electrolysis Method: In the process of electrolysis of potassium chloride Potassium chlorate can be produced. With the progress of this reaction, $mathrmKCl
O_3$ came out automatically. At the over of this if the electrodes are removed and the result is $mathrmKCl

Disproportionation Method: In a small amount of production of the $mathrmKCl
O_3$, this method is used.

Caustic Potash: It can be developed through passing chlorine gas into a hot solution of potassium hydroxide.


It can be used in many sectors, such as-

O_3$ is used as the oxidizing agent

It is used in the making of matches, explosives, fireworks.

In textile printing & bleach making, it is used.

It is used as an oxidizer in pyrotechnics

O_3$ is used in the production of oxygen.

In the making of smoke grenades, it is used

In laboratories, it is used as one of the most important chemical compounds.

It is used as a pesticide.

In the molten, it is used in the dramatic screaming jelly babies, grammy bear, etc.

Difference between Potassium Chlorate & Potassium Perchlorate

The main difference between Potassium Chlorate và Potassium Perchlorate is that the first one is highly reactive if compared with the second one. However, they both are ionic compounds and more specifically inorganic salt compounds. The chemical formula of Potassium Chlorate is $mathrmKCl
O_3$ và the chemical formula of Potassium Perchlorate is $mathrmKCl
O_4$. $mathrmKCl
O_3$ is used in the making of explosives and oxygen và $mathrmKCl
O_4$is used in explosive primers, & various propellants, flash compositions.


Potassium Chlorate is a chemical that is made with the combination of potassium, chlorine, và oxygen. Potassium Chlorate is crucial for industry use. Because of the high reactive, it is dangerous and that is the reason it should be used with great care. It is used in the making of explosives and fireworks. For industry use, it is prepared with the help of a salt metathesis reaction.
