1. What is magnesium chloride hexahydrate?
Magnesium chloride hexahydrate is the hydrated magnesium salt with the chemical formula MgCl₂·6H₂O. It contains six waters of crystallization for each magnesium chloride unit.
2. What is the difference between magnesium chloride and magnesium chloride hexahydrate?
Anhydrous magnesium chloride is MgCl₂, while magnesium chloride hexahydrate is MgCl₂·6H₂O. The hexahydrate contains approximately 59.0% MgCl₂ on a theoretical mass basis, with the remainder being water of crystallization.
3. Is magnesium chloride hexahydrate water soluble?
Yes. MgCl₂·6H₂O is highly soluble in water, making it useful for chemical processing and aqueous formulations.
4. What purity levels are available?
REG Metals can source grades ranging from technical/industrial purity to high-purity and reagent-grade material, depending on the application and supplier.
5. How should magnesium chloride hexahydrate be stored?
Because the material readily exchanges moisture with the atmosphere, it should generally be kept in tightly sealed, moisture-resistant packaging and stored in a dry environment.
6. Can REG Metals provide a Certificate of Analysis?
Yes. COA documentation is available as applicable, including chemical purity and impurity information provided by the manufacturer.
