Ammonium persulfate (NH 4 ) 2 S 2 O 8 is a strong oxidizing agent. It is very soluble in cold water, a large fall of temperature accompanying solution. It is a very strong oxidizing agent and 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 .
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.
