What is the function of anhydrous sodium sulfate

In life, many people have heard of the substance anhydrous sodium sulfate, but not many people really understand this substance. In order to better apply this substance, we still need to have a good understanding of the knowledge of this substance. If we want to understand the substance anhydrous sodium sulfate, we must first analyze the role of anhydrous sodium sulfate. So what is the role of anhydrous sodium sulfate? Let's listen to the editor's explanation below.

1. Introduction of anhydrous sodium sulfate:

Anhydrous sodium sulfate is also known as anhydrous sodium sulfate and sodium sulfate. Chemical formula: Na2SO4 Molecular weight: 142.04. White uniform fine granules or powder. Odorless, tastes salty and bitter. Density: 2.68g/cm. Melting point 884℃. It is easily soluble in water, and its solubility increases rapidly with increasing temperature within 0-30.4℃. Soluble in glycerol, insoluble in ethanol. The aqueous solution is neutral. When the aqueous solution is below 32.38°C, the decahydrate crystals precipitate. When the temperature is higher than 32.38℃, it begins to crystallize out as anhydrous sodium sulfate.

2. Application fields of anhydrous sodium sulfate:

It is mainly used as a filler for dyes and auxiliaries to adjust the concentration of dyes and auxiliaries to reach the standard concentration. It can also be used as an accelerator for direct dyes, sulphur dyes and vat dyes in dyeing cotton cloth, a retarder for direct acid dyes in dyeing silk and wool animal fibers, and a base colour protective agent during the refining of printed silk fabrics. In the papermaking industry, it is used as a cooking agent in the production of kraft pulp. In the pharmaceutical industry, it is used as an antidote for barium salt poisoning. In addition, it is also used in the glass and construction industries.

After understanding the role of anhydrous sodium sulfate, I hope this content can help all of us. In addition to understanding the role of anhydrous sodium sulfate, we also need to understand the common substances in life. Only in this way can we live a better life. For example, baking soda, a common substance in our daily life, can be used to remove scale.
