READY FOR SHIPMENT SODIUM SULPHITE ANHYDROUS (GLAUBERS SALT) We have Ex- Stock in Indonesia for immediate shipment from a reputed brand. Glauberâ??s salt is the decahydrate form of sodium sulfate. It is also known as mirabilite. Glauberâ??s salt is known to be a vitreous mineral with a white or colorless appearance that is formed as an evaporite from brines containing sodium sulfate. Glauberâ??s salt is widely used as a laxative in several medications. Furthermore, this compound is especially effective for the removal of excess drugs (such as paracetamol) in the body due to overdose. Glauberâ??s salt can also be employed during the production of chill mats for laptop computers. It can also be noted that the chemical industry makes extensive use of Glauberâ??s salt for the production of many commercially important chemicals.
