The chemical formula of MgSO4 is colorless and contains a soluble water soluble magnesium oxide of 16% or more. It has a white and crystalline appearance. It is usually found in the form of British salt of sulphate mineral in the form of heptahydrate (MgSO4 · 7H2). It plays a role in the formation of carbohydrates, proteins, fats and vitamins. It is a substance found in sea water that can crystallize as a hydrate in the form of small needles.
Mg 2 SO4 -2
Production and Reactions
The hydrated compound (MgSO4-H2O), called kizerit, is found as a mineral in nature. The magnesium sulfate MgSO 4 -7H 2O is produced by Sun.
In this sector magnesium sulfate salt is used in the British salt crystallization processes.
It is used to remove the Mg deficiency of chlorophyll in plants.
Medical; It is used to prevent premature birth of magnesium sulphate.
It is used as a thickener in some of the detergents, especially in winter.
