1、 GeneralState:

Sodium persulfate has molecular formula Na2S2O8 and molecular weight 238.18. It is white monoclinic crystal or powder with a specific gravity of 2.357. It is easily soluble in water. When heated to a higher temperature, it decomposes and releases oxygen to become sodium pyrosulfate. Sodium persulfate has excellent storage stability under the condition of low temperature drying, and is easy to decompose in case of humidity and catalyst. This product is a strong oxidant. Avoid direct contact with eyes, skin and clothing.
