Chemical Name: Magnesium Sulfate
Molecular Formula: MgSO4·7H2O, dry MgSO4·nH2O
Molecular Weight: 246.47 (Heptahydrate)
CAS: 10034-99-8 (Heptahydrate)
Character: It is a colorless prismatic or needle-shaped crystal with no odor. It has a cool, salty, and bitter taste. The relative density is 2.65. It remains stable in damp air below 48 degrees Celsius but easily effloresces in warm and hot air. Magnesium Sulfate is highly soluble in water (119.8 g/100 mL at 20°C) and glycerine, and slightly soluble in ethanol. The aqueous solution is neutral.
Company Name: Nanjing Jiayi Sunway Chemical Co., Ltd.
Each product is packed in a 25kg bag with a polyethylene inner layer and a composite paper outer layer.
