Magnesium sulfate anhydrous
High Solubility: Magnesium sulfate dissolves readily in water, facilitating its use across a wide spectrum of chemical and industrial processes.
Hygroscopic Nature: It exhibits deliquescent behavior, absorbing atmospheric moisture, which supports its function as a desiccant in controlled environments.
Stable and Safe: The compound remains stable under standard handling conditions and presents low risk, ensuring safe usage in diverse industrial settings.
Versatile Form: Available in both fine powder and crystalline forms, magnesium sulfate can be conveniently formulated for agricultural, pharmaceutical, and general industrial applications.
Magnesium sulfate anhydrous , commonly known as Epsom salt, bitter salt, or sulfur bitter, is a magnesium-containing compound. It usually occurs as colorless or white hygroscopic crystals or a white powdered form. The material is odorless and features a characteristic bitter-salty taste, exhibiting deliquescent behavior.
In its heptahydrate form, magnesium sulfate loses six water molecules at 150 °C and becomes fully anhydrous at 200 °C. The anhydrous variant has a density of 2.66, melts at 1124 °C, and decomposes at this temperature. It shows high solubility in water, moderate solubility in alcohol, ether, and glycerol, and is insoluble in acetone.
