Magnesium Sulfate - Home
Magnesium sulfate (MgSO4) is a chemical compound that contains one atom of magnesium bonded with one sulfate ion. Magnesium sulfate is found most commonly in the form of magnesium sulfate heptahydrate (MgSO4 • 7H2O), making it highly soluble in water. When bonded with water in this way, magnesium sulfate is commonly known as Epsom salts.

Project Profile On Magnesium Sulphate
Magnesium sulphate is a chemical compound containing Magnesium Sulphur & Oxygen with the formula MgSO 4. It has a tendency to absorb water from the atmosphere, so it is often found in hydrated form i.e. MgSO 4. 7H 2O. Magnesium Heptahydrate, also known as Epsom Salt is the most commonly available form of Magnesium sulphate.
