anhydrous sodium sulfate

Sodium sulfate is a salt formed by the combination of sulfate and sodium ions. Sodium sulfate dissolves in water and its aqueous solution is weakly alkaline, soluble in glycerol but insoluble in ethanol. Inorganic compounds, sodium sulfate decahydrate, also known as Glauber's salt, high purity, fine particles of anhydrous material called Yuan Mingfen, exposed to air, easy to absorb water to produce sodium sulfate decahydrate, sodium sulfate decahydrate commonly known as Glauber's salt. Yuan Ming powder, white, odorless, bitter crystal or powder, hygroscopicity. The appearance is colorless, transparent, large crystals or small granular crystals.
