Ammonium persulfate is a white singlecrystal with a density of 1.98. It decomposescompletely at 120 °C, and can be stored fora long time when it is completely dried.However。it decomposes gradually afterabsorbing moisture and releases oxygenand ozone. It dissolves in water and decom-poses when heated. It can be used aschemical reagent,oxidant，bleaching agent,deodorizer and initiator of monomer polym-erization. It also has the advantages ofconvenience and safety.

Molecular Formula: Na2S2O8Sodium Persulfate is a kind of whitetasteless crystal or powder，which isdecomposed by ethanol and has goodstability at room temperature. It is oftenused as strong oxidant,and also asinitiator of monomer polymerization. ltalmost does not absorb moisture，it iseasy to store, easy to use and safe.
