1. Product info.
Molecular Formula: Na2S2O8
Molecular weight: 238.13
Sodium persulfateis a white,crystalline,odourless salt.It is used as initiator for the Polymerization of monomers and as a strong oxidizing agent in many applications.It has the particular advantage of being almost non - hygroscopic,of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.
