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 silicide in the interior of the unit cell. The coordination numbers of Si and Mg are eight and four, respectively. Magnesium silicide Magnesium silicide, MgSi, is an inorganic compound consisting of magnesium and silicon. It can be produced by heating silicon dioxide, SiO, found in sand, with excess magnesium. The process first forms silicon metal and magnesium oxide, and, if an excess of magnesium is used, the silicide is formed: If an excess of Mg is present, MgSi is formed from the reaction of the remaining magnesium with the silicon: These reactions proceed exothermically. Magnesium silicide is used to create aluminium
