Description

 

Magnesium sulfate is a chemical compound containing magnesium, sulfur and oxygen. It is used as a drying agent. In agriculture and gardening, magnesium sulfate is used to correct magnesium deficiency in soil, since magnesium is an essential element in the chlorophyll molecule. It is commonly used as a desiccant in organic synthesis due to its affinity for water. It is used in bath salts, particularly in flotation therapy where high concentrations raise the bath water's specific gravity, effectively making the body more buoyant. This property is also used to restore some Lava lamps damaged by being shaken by exchanging the water and adding drops of a concentrated solution until sustainable buoyancy is reached. It is also used as a reactive compound in the manufacture of Black Powder, where it contributes to a violent burn rate thus reducing material costs. Oral magnesium sulfate is commonly used as a saline laxative. Epsom salt is also available in a gel form for topical application in treating aches and pains.
