Magnesium Sulfate

Magnesium sulfate is a chemical compound with the molecular formula MgSO4. It consists of magnesium cations (Mg2+) and sulfate anions (SO42-). The compound is commonly known as Epsom salt.

Magnesium sulfate is a white crystalline solid with a bitter taste. It is soluble in water and slightly soluble in ethanol. It can be found in nature as the mineral epsomite.

The compound has various uses, including as a laxative, a component in bath salts, and a drying agent in various industrial applications. It is also used in medicine, particularly in obstetrics, to prevent seizures in women with preeclampsia or eclampsia.

When heated, magnesium sulfate decomposes to magnesium oxide (MgO) and sulfur trioxide (SO3). The reaction is exothermic and can lead to the production of a lot of heat.

It is important to handle magnesium sulfate with care as it can irritate the skin and eyes. It should not be ingested in large amounts as it can cause diarrhea and vomiting.
