Technol. Avoid dust formation.
It is the sodium salt of peroxydisulfuric acid, H2S2O8, an oxidizing agent.
However, high concentrations of partially neutralized acrylic acid (high solids) decrease the decomposition rate of persulfate relative to that in the presence of acrylic acid (not neutralized). It is almost non-hygroscopic and has good shelf-life. The presence of an intermediate with composition K 2 SO 5 was detected. Exposure to moisture. Proceeding from KHSO 4, K 2 S 2 O 8, NaHSO 4 and Na 2 S 2 O 8, potassium- and sodium-pyrosulfates were prepared and their thermal decomposition was investigated by a T.G.A. Chemists call it sodium peroxosulphate, short form NaPS, sodium persulfate is its trade name, the salt of peroxodisulphuric acid. Ammonium persulfate (APS) and potassium persulfate (KPS) both are commonly used as redox initiator in radical polymerization reaction.

It is a white solid that dissolves in water. Thermal Initiators: Decomposition Rate and Half-Life Fig 1: Relationship of Half Life (t FFF) to Decomposition Rate (k d).
Brown, and David Robinson.
"Novel activation technologies for sodium persulfate in-situ chemical oxidation." The activation energy and rate constants for the decomposition of sodium persulfate in the presence of acrylic acid have been determined for monomer compositions representative of those used in a polymerization process to prepare sodium polyacrylate superabsorbent polymers. The salt is prepared by the electrolytic oxidation of The standard redox potential of sodium persulfate into hydrogen sulfate is 2.1 V, which is higher than that of hydrogen peroxide (1.8 V) but lower than ozone (2.2 V).However, there are a few drawbacks in utilizing platinum anodes to produce the salts; the manufacturing process is inefficient due to oxygen evolution and the product could contain contaminants coming from platinum corrosion (mainly due to extremely oxidizing nature of the sulfate radical).
