Magnesium Sulfate

Magnesium sulfate, also known as Magnesium salt and Epsom salt, is a chemical compound of oxygen, sulfur, and magnesium that occurs naturally in seawater and mineral springs. One of the most important uses of this substance is in medicine, agriculture, and pharmaceutical. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.

Physical and Chemical Properties:

Magnesium sulfate with the chemical formula MgSO₄ is colorless or white crystals with a cool, salty, and bitter taste, dissolves rapidly in water, and is insoluble in ethanol (alcohol). The anhydrous form of this compound has the ability to absorb water quickly and easily absorbs moisture from the air, so it is sold as a desiccant. Although this feature makes it difficult to accurately measure its weight. In the table below some of the chemical and physical properties of this product are mentioned:

Chemical Structure Depiction

The Production Process of Epsom salt:

Epsom salt can be prepared by reacting magnesium carbonate or magnesium oxide with sulfuric acid. Another method is to use industrial seawater or industrial effluents containing magnesium to precipitate magnesium hydroxide and react the precipitate with sulfuric acid.

MgCO₃ + H2SO₄ → MgSO₄+ H₂CO₃

Magnesium Sulfate Uses:

Magnesium sulfate has a wide range of uses in agriculture, industry, food additives, animal feed, cosmetics, and medicine. In this section, we describe some of the applications of this chemical:

Food:

This salt is used to make beer. It may also be used as a coagulant to make tofu. Like Malic acid

Medical:

In general, the human body needs a certain amount of magnesium (about 400 mg per day), which is why MgSO4 is used to control low levels of magnesium in the blood. In some cases, it is also used to treat asthma, eclampsia, and stomach ailments.

Construction:

The combination of magnesium oxide and magnesium sulfate solution is used in the preparation of cement that is more resistant. Just keep in mind that these types of cement are not waterproof and can be used in the production of lightweight insulation panels.

Chemical:

Anhydrous magnesium sulfate, due to its structural properties, shows a great tendency to moisture, in other words, it can be called a moisture absorber, so in the synthesis of organic matter in laboratories, it is used as a desiccant.

Agriculture:

The agricultural industry has always been one of the largest markets for Epsom salt. This compound is used in agricultural industries to prepare agricultural fertilizers to increase the amount of magnesium or soil sulfur, this substance is usually used on potted plants, or products that need magnesium such as potatoes, tomatoes, and Carrots used. The solubility of this material is higher than other magnesium-based materials used for soil remediation. That is why it is used more. Solutions of this substance have an almost neutral pH compared to the alkaline magnesium salts found in limestone. For this reason, they do not cause any significant change in soil pH.

Other Industrial Uses:

Magnesium sulfate is used in the manufacture of paper, rayon, and silk. It is also used in the leather industry to increase the thermal resistance of leather. In small industries, magnesium sulfate is used as a stabilizer of calcium hydrogen phosphate in toothpaste.

Safety Information:

Consumption of magnesium sulfate in high concentrations can cause a condition called hypermagnesemia as well as symptoms such as abdominal pain, diarrhea, and vomiting. When heated to the point of decomposition, it releases toxic and corrosive sulfur oxides that are dangerous to health.

Packing and Storage:

Keep containers tightly closed in a dry, cool, and well-ventilated place.
