Product Description

Sodium sulfate 

is a salt formed by the combination of sulfate radical and sodium ion. The chemical formula is Na2SO4. Sodium sulfate is soluble in water. Most of its solutions are neutral, soluble in glycerol but insoluble in ethanol. Inorganic compounds, anhydrous substances with high purity and fine particles, are called sodium sulphate. Sodium sulphate, white, odorless, bitter crystal or powder, hygroscopic. The shape is colorless, transparent, large crystal or granular small crystal. Sodium sulfate is easy to absorb water when exposed to the air, forming sodium sulfate decahydrate, also known as mirabilite, which is alkaline. It is mainly used for manufacturing water glass, glass, enamel, pulp, refrigeration mixture, detergent, desiccant, dye diluent, analytical chemical reagent, medicine, feed, etc. At 241 ºC, sodium sulfate will turn into hexagonal crystal. Sodium sulfate is one of the most commonly used post-treatment desiccants in organic synthesis laboratories. Upstream raw materials include sulfuric acid, etc.
