Potassium Chlorate vs. Potassium Perchlorate: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on December 2, 2023
Potassium chlorate (KClO3) is a compound with three oxygen atoms, while potassium perchlorate (KClO4) has four oxygen atoms and is more oxidizing.
Key Differences
Potassium chlorate, KClO3, contains one chlorine and three oxygen atoms. In contrast, potassium perchlorate, KClO4, has one extra oxygen atom.
The additional oxygen in potassium perchlorate makes it a stronger oxidizing agent than potassium chlorate.
Potassium chlorate is often used in safety matches and fireworks, while potassium perchlorate's higher stability makes it suitable for more sensitive applications.
In terms of chemical synthesis, potassium chlorate can be made by electrolysis of potassium chloride, whereas potassium perchlorate is often produced by further oxidizing potassium chlorate.
Both compounds are white, crystalline substances, but potassium perchlorate has a lower solubility in water compared to potassium chlorate.
