Ammonium persulfate (NH4)2S2O8 is a strong oxidizing agent. It is very soluble in cold water, a large fall of temperature accompanying solution. It is a radical initiator. It is used to etch copper on printed circuit boards as an alternative to ferric chloride solution.[1] It is also used along with tetramethylethylenediamine to catalyze the polymerization of acrylamide in making a polyacrylamide gel.
Ammonium persulfate was prepared by H. Marshall by the method used for the preparation of potassium persulfate — by the electrolysis of a solution of ammonium sulfate and sulfuric acid.[2]
Ammonium persulfate is the main component of Nochromix. On dissolving in sulfuric acid, it is used to clean laboratory glassware as a metal-free alternative to chromic acid baths.[3] It is also a standard ingredient in western blot gels.
