Preparation

Magnesium bromide is prepared by treating MgO with hydrobromic acid and then crystallization above 0.0°C in solution. The product is the hexahydrate salt: MgO＋2HBr→MgBr2＋H2O→MgBr2·6H2O The anhydrous form may also be prepared by heating the hexahydrate with dry HBr gas. This compound can also be formed directly from the elements: Mg＋Br2→MgBr2

Production Methods

It is also formed by the reaction of magnesium carbonate and hydrobromic acid. The solubility of magnesium bromide is 101 g/ 100 mL of water at 20 °C; the solubility of the hexahydrate is 160 g/ 100 mL of 95% ethanol at 20 °C.
