Magnesium sulfate production method:

Magnesium sulfate with 7 molecules of crystalline water can be prepared by reacting sulfuric acid with magnesium carbonate or magnesium oxide, which is a type of neutralization reaction. But it is usually obtained directly from natural sources. Magnesium sulfate without crystallization water is obtained only by dehydrating the juice of magnesium sulfate.
