CAS No   7727-54-0
     
Application / Uses Preparation
Ammonium persulphate (NH4)2S2O8 is a strong oxidizing agent. It is very soluble in water; the dissolution of the salt in water is endothermic. It is a radical initiator. It is used to etch copper on printed circuit boards as an alternative to ferric chloride solution.

CAS No   7727-21-1
     
Application / Uses Preparation
Potassium persulphate can be prepared by electrolysis of a mixture between potassium sulfate and hydrogen sulfate at a high current density.

CAS No   7775-27-1
     
Application / Uses Preparation
Sodium persulphate (Na2S2O8) is a chemical compound. It is a strong oxidizer. It is a severe irritant of skin, eyes, and respiratory system. It is almost non-hygroscopic and has particularly good ability to be stored for long time. It is easy and safe to handle. It is not combustible, but releases oxygen easily and assists combustion of other materials.
