Magnesium Sulfate Heptahydrate CAS#10034-99-8
Highly Soluble in Water: Easily dissolves in water, making it suitable for various applications requiring water solubility.
Hygroscopic Nature: Demonstrates hygroscopic properties, absorbing moisture effectively.
Stable and Non-flammable: Stable under normal conditions and non-flammable, ensuring safety during storage and use.
Versatile in Different Environments: Soluble in water and acid, with limited solubility in alcohol and glycerol, offering flexibility in formulation.
Magnesium sulfate heptahydrate (MgSO₄·7H₂O) appears as white or colorless, needle-like or columnar crystals. It is odorless, cool to the touch, and has a faintly bitter taste. With a molecular weight of 246.47 and a specific gravity of 1.68, it is highly soluble in water but only slightly soluble in ethanol and glycerol. At 67.5°C, it dissolves in its own crystallization water, further demonstrating its hygroscopic nature.
