SODIUM SULFATE DECAHYDRATE Structural

What is SODIUM SULFATE DECAHYDRATE?

Chemical properties

White or almost white, crystalline powder or colourless, transparent crystals.

The Uses of SODIUM SULFATE DECAHYDRATE

Sodium sulfate decahydrate is used in manufacturing paper pulp by the Kraft Process. Other uses are in manufacturing glass and ultramarine; in dyeing and printing textiles; as a filler in synthetic detergents; and for standardizing dyes. A major use of anhydrous sodium sulfate is as an agent to remove water from organic solvents and their extracts for organic synthesis and instrumental analysis. Sodium sulfate decahydrate is a common laboratory reagent. Also, it is used to prepare other sodium salts.

The Uses of SODIUM SULFATE DECAHYDRATE

Sodium sulfate decahydrate is used as a laboratory reagent to precipitate protein. It is largely used as filler in powdered home laundry detergents. It facilitates in leveling, reducing negative charges on fibers, thereby allows dye to penetrate evenly. It avoids the corrosion of stainless steel vessels used in dyeing. It is also used as a laxative and effectively replaces the drug paracetamol in the body.

The Uses of SODIUM SULFATE DECAHYDRATE

Sodium sulfate decahydrate may be used to deepen the color while dyeing cotton fabrics.6

What are the applications of Application

Sodium sulfate decahydrate is a neutral salt, forms aqueous solutions with ph of ~7

Definition

ChEBI: Sodium sulfate decahydrate is a hydrate. It has a role as a cathartic. It contains a sodium sulfate.

General Description

Sodium sulfate decahydrate (Glauber′s salt, mirabilite, Na2SO4·10H2O) is the decahydrate salt of sodium sulfate. Its crystal structure has been investigated by single-crystal neutron diffraction studies. Its crystallization enthalpy has been evaluated. It can be synthesized by reacting MnSO4, thiophene-2,5-dicarboxylic acid and sodium glutamate.

Purification Methods

Crystallise sodium sulfate from water at 30o (1.1mL/g) by cooling to 0o. It becomes anhydrous at 32o.
