Potassium Chlorate - KClO3

What is Potassium Chlorate?

Potassium Chlorate is an inorganic compound with chemical formula KClO3.

It is also known as Fekabit or Kaliumchlorat. It is very flammable when mixed with combustible materials. It is a compound containing potassium, oxygen, and chlorine. It appears as a white crystalline substance in its pure form. It is the most widely used chlorate industry.

The aqueous solution of potassium chlorate is a colourless liquid that is denser than water. It could be toxic when ingested. When it comes in contact it can irritate your eyes, skin, mucous membranes. It has a cooling and saline taste.

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. Consider hot calcium hydroxide.

Step 2. Pass chlorine into it.

Step 3. Add potassium chloride.

2. Potassium chlorate produced by disproportionation:

Step 1. Consider a sodium hypochlorite solution

Step 2. Metathesis reaction along with potassium chloride

3. Method three:

Step 1. Consider a hot solution of caustic potash

Step 2. Pass chlorine gas into it
