What is sodium persulfate used for?
Sodium Persulfate is a white crystalline powder. It is used as a bleaching agent for fats, textiles and hair, a battery depolarizer, and in emulsion polymerization.
What is the chemical formula for sodium persulfate?
Na2S2O8Sodium persulfate / Formula
How do you dispose of sodium persulfate?
* Cover with dry lime, sand or soda ash and place in covered containers for disposal. * Ventilate and wash area after clean-up is complete. * It may be necessary to contain and dispose of Sodium Persulfate as a HAZARDOUS WASTE.
Is sodium persulfate an acid?
About Sodium Persulfate Sodium Persulfate is a moderately water and acid soluble Sodium source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal.

What is persulfate oxidation?
3.1.1 Direct Oxidation Persulfate reacts directly with many organic materials, exchanging electrons in a process known as. direct oxidation. Persulfate is considered a powerful direct oxidant as it has a theoretical standard. oxidation potential of 2.0V (for the reaction S 2O8. 2- + 2e- → 2SO4.
Is persulfate the same as sulfate?
What happens when Na2SO4 is heated?
Phase change energy storage mechanism can be summar- ised as chemical equation (1). After Na2SO4·10H2O crystal is heated to melt. It removes bound water and absorbs heat. Conversely, this process will release heat when sodium sulphate combines with water molecules to form crystal.
How is a sulfate ion formed?
The sulphate ion is mainly composed of sulphur and oxygen atoms. Here, sulphur is the central atom and it is surrounded by four oxygen atoms that are located at equal distances in the plane. As for the bonding, 2 of the oxygen atoms form S=O. bonds and the other two form S-O- bonds.
What are persulfates?
Persulfates are chemical compounds which contain either the peroxomonosulfate (or peroxymonosulfate) ion, SO52−, or the peroxodisulfate (or peroxydisulfate) ion, S2O82−.
