What Is The Formula For Magnesium Bromide?
In its anhydrous form, it is hygroscopic hexagonal crystal white in colour. In its hexahydrate for, it is colourless monoclinic crystal. It can be prepared by the following method
- Treating hydrobromic acid (HBr) with magnesium oxide (MgO) and crystallizing the product.
- It can also be synthesized by reacting magnesium carbonate (MgCO3) and hydrobromic acids (HBr).
On completing this it is evaporated and the solid leftover is collected. It is soluble in water as well as alcohol. It is naturally found in some minerals such as carnallite and bischofite.
