MgSO

MgSO is the chemical formula for magnesium sulfate. It is an inorganic salt with the formula MgSO. Magnesium sulfate is commonly encountered as the heptahydrate, MgSO4·7H2O, which is the mineral epsomite. It is a white crystalline solid that is highly soluble in water.

Magnesium sulfate has a wide range of applications. In medicine, it is used as a laxative and to treat magnesium deficiencies. It can also be administered intravenously to treat conditions such as pre-eclampsia and eclampsia. In agriculture, magnesium sulfate is used as a fertilizer to provide magnesium and sulfur to plants, which are essential nutrients for growth. It is particularly useful for correcting magnesium deficiencies in crops like tomatoes, peppers, and potatoes.

In industry, magnesium sulfate is used in the production of textiles, paper, and cement. It can also be employed as a drying agent and as a component in fire retardants. In laboratory settings, it is frequently used as a drying agent for organic solvents. The crystalline form of magnesium sulfate, particularly the heptahydrate, is known as Epsom salt and is often added to bathwater for its purported therapeutic benefits, such as soothing sore muscles. Anhydrous magnesium sulfate is a common drying agent in organic synthesis.
