Magnesium Sulfate
Molecular Formula: MgSO 4.7H 2 O.
Molecular weight: 246.48.
Characteristics:
--White exiguous acicular or oblique-pillar crystal. Smell-less, tast-bitter. Easily efflorescent at dry air.
--Speciific gravity is 1.68.
--Freely soluble in water. Solublein its own waterat 67.5oC. Slightly soluble in ethanol and glycerin.
--Dcomposing is heatedup. Lossing 4 crystal waterat 70-80oC. About at 200oC, lossing all of its crystal water becomes anhydrous compounds.
Use:
