Description

An inorganic compound that is the sodium salt of peroxydisulfuric acid is called sodium persulfate. This substance with the formula Na2S2O8 is a white solid and soluble in water.

Properties:

Chemical formula Na2S2O8
Molar mass 238.10 g/mol
Appearance White powder
Density 2.59 g/cm3
Melting point 180 °C (356 °F; 453 K) decomposes
Solubility in water 55.6 g/100 ml (20 °C)
CAS Number 7775-27-1

Production:

This salt is obtained from the electrolytic oxidation of sodium bisulfate and its reaction equation is as follows:

2 NaHSO4 → Na2S2O8 + H2

The oxidation process is carry out in the platinum anode. Of course, the use of platinum rods causes problems in the salt production process. In this process, due to the ineffective evolution of oxygen, the product may contain impurities caused by platinum corrosion. For this reason, boron-doped diamond electrodes were proposed as an alternative to platinum.

Applications of sodium persulfate:

It is usually use as a radical initiator for polymerization reactions; It is also use for quick curing of low formaldehyde adhesives. On the other hand, this substance is use as a bleach in hair care products and as a substitute for ammonium persulfate for printed circuits. It can be used as a soil softener to improve soil and groundwater, make color materials, descaling agent, bleach activator and starch modification.

Storage :

Store this material in a dry place, away from incompatible materials or mixtures, at a temperature of 15 to 25 degrees Celsius.
