Ammonium Persulfate 98% ACS Reagent

Ammonium persulfate 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. It is also used along with tetramethylethylenediamine to catalyze the polymerization of acrylamide in making a polyacrylamide gel. Ammonium persulfate is a white crystalline solid. A strong oxidizing agent. Does not burn readily, but may cause spontaneous ignition of organic materials. Used as a bleaching agent and as a food preservative.
