Thermal Decomposition of Potassium Chlorate

2KClO3 → 2KCl + 3O2

Genel Bakış

Potassium chlorate decomposes when heated (with MnO2 catalyst at ~200 C, or without catalyst at ~400 C) to form potassium chloride and oxygen gas. This reaction was historically used as a laboratory source of oxygen gas before compressed gas cylinders became widely available.

Günlük Örnek

Safety matches contain potassium chlorate as the oxidizer, which decomposes and releases oxygen when struck to help ignite the match.

Endüstriyel Önemi

Used in pyrotechnics, matches, and as a laboratory oxygen source. Potassium chlorate was historically used as a primary explosive, though safer alternatives have largely replaced it.
