Magnesium Sulphate

Magnesium sulfate or magnesium sulphate (in English-speaking countries other than the US) is a chemical compound, a salt consisting of magnesium cations and sulfate anions. It is a white crystalline solid, soluble in water but not in ethanol.

Magnesium sulfate is usually encountered in the form of a hydrate, for various values of n between 1 and 11. The most common is the heptahydrate, known as Epsom salt, which is a household chemical with many traditional uses, including bath salts.

Usage of Magnesium Sulphate:

Agriculture, Food preparation, Chemistry, Construction, Aquaria and other.

The main use of magnesium sulfate is in agriculture, to correct soils deficient in magnesium (an essential plant nutrient because of the role of magnesium in chlorophyll and photosynthesis). The monohydrate is favored for this use; by the mid 1970s, its production was 2.3 million tons per year. The anhydrous form and several hydrates occur in nature as minerals, and the salt is a significant component of the water from some springs.
