Magnesium Sulphate

About

Magnesium Sulphate

Grade : Extra pure LR/ AR/ ER ACS/ AR ACS

Magnesium Sulphate (or magnesium sulfate) is an inorganic salt (chemical compound) containing magnesium, sulfur, and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4•7H2O), commonly called Epsom salt. GRADES: EXTRA PURE / LR / AR / GR. MOLAS MASS: 120.366g/mol

Appearance

Magnesium Sulphate is White Crystalline Solid.

Properties

Magnesium sulphate is highly soluble in water. The anhydrous form is strongly hygroscopic, and can be used as a desiccant. It is the primary substance that causes the absorption of sound in seawater (acoustic energy is converted to thermal energy). Absorption is strongly dependent on frequency: lower frequencies are less absorbed by the salt, so that the sound travels much farther in the ocean. Boric acid also contributes to absorption, but the most abundant salt in seawater, sodium chloride, has negligible sound absorption.

Uses

In medical field, pregnancy, agriculture, used as a desiccant in organic synthesis due to its affinity for water, in bath salts used as a brewing salt in beer production to adjust the ion content of the brewing water and enhance enzyme action in the mash or promote a desired flavour profile in the beer.
