Chemical Identity and Structure

Magnesium Chloride Hexahydrate is an inorganic salt composed of one magnesium ion (Mg²⁺) and two chloride ions (Cl⁻), hydrated with six molecules of water. Its chemical formula, MgCl2·6H2O, clearly indicates its hydrated nature. This compound is highly soluble in water, forming colorless or white crystalline solids. The hexahydrate form is the most common and readily available. The presence of water molecules in its crystal structure influences its physical properties and handling requirements.

Key Physical and Chemical Properties:

  • Appearance: Typically appears as white or colorless crystals, flakes, or powder.
  • Solubility: Exhibits high solubility in water, readily dissolving to form clear solutions. It is also soluble in alcohol.
  • Melting Point: The hexahydrate form melts at approximately 116.7 °C, often with decomposition.
  • Hygroscopic Nature: Magnesium Chloride Hexahydrate readily absorbs moisture from the air, meaning it is deliquescent. This property necessitates proper storage in airtight containers.
  • pH: Aqueous solutions typically have a slightly acidic to neutral pH, generally between 4.5 and 7.0 for a 5% solution.
  • Purity: Available in various purity levels, such as 46% and 99%, depending on the intended application.

Safe Handling and Storage Practices

Due to its hygroscopic nature, Magnesium Chloride Hexahydrate should be stored in cool, dry conditions in tightly sealed containers to prevent caking and degradation. When handling the material, appropriate personal protective equipment (PPE) such as gloves, safety glasses, and protective clothing should be worn. While generally considered safe for its intended uses, avoiding dust inhalation and skin or eye contact is important. Always consult the Material Safety Data Sheet (MSDS) provided by the manufacturer for comprehensive safety information before handling or purchasing.
