A sodium salt of sulfuric acid and also which is used for the manufacture of detergents and in the kraft process of paper pulping is known as sodium sulphate. Sodium sulphate is highly used in commodity industry and also in the thermal storage as sodium sulphate is very cheap material and also is used as filler in powdered home for laundry detergents as it is domestic use or domestic application. In laboratories it is widely used for an inert drying agent used for removing traces of water from organic solutions as these are more efficient but is slow in acting than that of similar agent known as magnesium sulfate. Sodium sulphate is considered to be non toxic but is required to be handled with care.
The dust of this agent can cause temporary asthma, eye irritation as the risk can be prevented by using eye protection. The type of sodium sulphate is anhydrous sodium sulphate which is in the hygroscopic form and is very much white in powder which has no odor. Anhydrous sodium sulphate is very much soluble in water but insoluble in ethanol and is also stable under ordinary conditions but at a high temperature which is then reduced to sodium sulfide. Anhydrous sodium sulphate does not react with oxidizing agents which are at normal temperature. Few facts about anhydrous sodium sulphate are that this compound is mostly found in nature in the form of mineral known as thenardite as anhydrous sodium sulphate tends to attract iron compounds and organic compounds.
Anhydrous sodium sulphate very much have many uses which are mainly used in laundry detergents and sodium sulphate is used in the manufacturing of wood pulp which is for kraft process and is also used in the glass industry thus for removing air bubbles from the molten glass and other uses of this anhydrous sodium sulphate includes in the manufacture of starch, carpet fresher's, in frosting windows etc.
