Sodium persulfate                                                                                Molecular formula: Na2S2O8                            Molecular weight: 238.13Structural formula:Characteristics: Sodium persulfate is a white, crystalline, odourless salt. It is used as initiator for the polymerisation of monomers and as a strong oxidizing agent in many application. It has the particular advantage of being almost non-hygroscopic, henan kingway chem,of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.
