Magnesium Sulfate: Anhydrous vs. Monohydrate vs. Heptahydrate
Magnesium sulfate is an important magnesium salt widely used in agriculture, animal nutrition, industry, food processing, and pharmaceuticals. According to the amount of crystallization water, the most common commercial forms include: Anhydrous Magnesium Sulfate: MgSO₄ Magnesium Sulfate Monohydrate: MgSO₄·H₂O Magnesium Sulfate Heptahydrate: MgSO₄·7H₂O All three provide magnesium ions (Mg²⁺) and sulfate ions after dissolution. However, differences in crystallization water resu

Ferrous Sulfate Hydrates: Monohydrate, Tetrahydrate and Heptahydrate
Ferrous sulfate is an important source of divalent iron used across agriculture, animal nutrition, water treatment and various industrial processes. Commercial and naturally occurring ferrous sulfate exists in several hydration states. Among them, ferrous sulfate heptahydrate (FeSO₄·7H₂O) and ferrous sulfate monohydrate (FeSO₄·H₂O) are the most commercially relevant, while ferrous sulfate tetrahydrate (FeSO₄·4H₂O) is mainly encountered as an intermediate hydration phase. Alth
