Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO3. Most sulfur contains trace quantities of sulfur-containing acids, and these can cause spontaneous ignition - "Flowers of sulfur" or "sublimed sulfur", despite the overall high purity, contains significant amounts of sulfur acids. Formula for Potassium chloride is KCl.

Potassium chlorate immediately decomposes if heated in presence of a catalyst such as MnO 2. %%EOF When KClO3 is heated strongly, it breaks down releasing oxygen gas and leaving behind a thermally stable (i.e., heat-insensitive) solid residue of an ionic potassium compound. When significant effort was made to reduce the availability of ammonium nitrate fertilizer in Afghanistan, IED makers started using potassium chlorate as a cheap and effective alternative. Since 2005, a cartridge with potassium chlorate mixed with lactose and rosin is used for generating the white smoke signaling the election of new pope by a papal conclave.[10]. Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride:[8], It can also be produced by passing chlorine gas into a hot solution of caustic potash:[9]. 0000001057 00000 n А.
