Magnesium sulfate anhydrous CAS#7487-88-9
1. High Solubility: Magnesium sulfate is highly soluble in water, making it ideal for use in various chemical processes and applications.
2. Hygroscopic Nature: Its deliquescent properties allow it to absorb moisture from the environment, which is useful in certain industrial applications like drying agents.
3. Stable and Safe: It is stable under normal conditions and poses minimal hazards, making it safe for handling in a range of industries.
4. Versatile Form: Available in fine powder or crystal form, magnesium sulfate can be easily incorporated into formulations for agricultural, medicinal, or industrial uses.
Magnesium sulfate, also referred to as Epsom salt, bitter salt, or bitter sulfur, is a compound containing magnesium. It typically presents as colorless or white hygroscopic crystals or a white powder. The substance is odorless but has a distinctly bitter and saline taste. It exhibits deliquescent properties.
The heptahydrate form of magnesium sulfate loses six molecules of water at 150°C and becomes completely anhydrous at 200°C. The anhydrous form has a density of 2.66, a melting point of 1124°C, and decomposes at this temperature. It is highly soluble in water, moderately soluble in alcohol, ether, and glycerol, but insoluble in acetone.
