''''Ammonium persulfate''' is a very strong oxidizer used for industrial cleaning and decontamination, as well as a strong [[radical initiator]] often used to promote polymerization reactions. Its oxidation potential, at 2.1 V, is only slightly weaker than [[ozone]] (O<sub>3</sub><sup>2</sup><sup>-</sup>, 2.2) but stronger than both [[hydrogen peroxide]] (H<sub>2</sub>O<sub>2</sub>, 1.8 V) and [[permangenate]] (MnO<sub>4</sub>, 1.7V). It is also widely used in [[polyacrylamide gel electrophoresis]] (PAGE) within biochemistry labs. The persulfate radical is particularly stable relative to many other radicals, and it is often stabilized even more by the addition of [[tetramethylethylenediamine]] (TEMED). | |||

'Ammonium persulfate is a very strong oxidizer used for industrial cleaning and decontamination, as well as a strong radical initiator often used to promote polymerization reactions. Its oxidation potential, at 2.1 V, is only slightly weaker than ozone (O32-, 2.2) but stronger than both hydrogen peroxide (H2O2, 1.8 V) and permangenate (MnO4, 1.7V). It is also widely used in polyacrylamide gel electrophoresis (PAGE) within biochemistry labs. The persulfate radical is particularly stable relative to many other radicals, and it is often stabilized even more by the addition of tetramethylethylenediamine (TEMED).
