Anhydrous magnesium sulfate is commonly used as a desiccant in organic synthesis owing to its affinity for water and compatibility with most organic compounds. During work-up, an organic phase is treated with anhydrous magnesium sulfate. The hydrated solid is then removed by filtration, decantation, or by distillation (if the boiling point is ...
Leonite is a hydrated double sulfate of magnesium and potassium. It has the formula K 2 SO 4 ·MgSO 4 ·4H 2 O. The mineral was named after Leo Strippelmann, who was director of the salt works at Westeregeln in Germany. [4] The mineral is part of the blodite group of hydrated double sulfate minerals. [3]
Kieserite, or magnesium sulfate monohydrate, is a hydrous magnesium sulfate mineral with formula (MgSO 4 ·H 2 O). It has a vitreous luster and it is colorless, grayish-white or yellowish. Its hardness is 3.5 and crystallizes in the monoclinic crystal system. Gunningite is the zinc member of the kieserite group of minerals. [5]
Sodium magnesium sulfate is a double sulfate of sodium and magnesium. There are a number of different stoichiometries and degrees of hydration with different crystal structures, and many are minerals. Members include: Blödite or bloedite: sodium magnesium sulfate tetrahydrate Na 2 Mg(SO 4) 2 •4H 2 O [1]

Epsomite forms as encrustations or efflorescences on limestone cavern walls and mine timbers and walls, rarely as volcanic fumarole deposits, and as rare beds in evaporite layers such as those found in certain bodies of salt water.
Leafy greens—like spinach, kale, collards, lettuce and cabbage—deliver fiber and water, meaning they'll help keep you hydrated and fill you up with lots of nutrients in a few calories.
Meridianiite is the mineral consisting of magnesium sulfate undecahydrate, MgSO 4 ·11H 2 O.It is colorless transparent crystalline salt that precipitates from solutions saturated in Mg 2+ and SO 4 2− ions at temperatures less than 2 °C. [4]
