Magnesium sulfate magnesium sulfate are also nearly neutral, compared with alkaline salts of magnesium as found in limestone; therefore, the use of magnesium sulfate as a magnesium source for soil does not significantly change the soil pH. Magnesium sulfate is used as a brewing salt in beer. It may also be used as a coagulant for making tofu. Anhydrous magnesium sulfate is commonly used as a desiccant in organic synthesis due to its affinity for water. During work-up, an organic phase is treated with anhydrous magnesium sulfate. The hydrated solid is then removed with filtration or decantation. Other inorganic sulfate salts such
Magnesium acetate Magnesium acetate Anhydrous magnesium acetate has the chemical formula Mg(CHO) and in its hydrated form, magnesium acetate tetrahydrate, it has the chemical formula Mg(CHCOO) • 4HO. In this compound magnesium has an oxidation state of 2. Magnesium acetate is the magnesium salt of acetic acid. It is deliquescent and upon heating, it decomposes to form magnesium oxide. Magnesium acetate is commonly used as a source of magnesium in biological reactions. Magnesium acetate appears as white hygroscopic crystals. It smells like acetic acid and is soluble in water. When it is in an aqueous solution its pH will be on the
