What is MgCl2? Important knowledge about MgCl2.

  1. MgCl2, also known as Magnesium Chloride, is an odorless, colorless crystalline solid with a slightly bitter, salty taste. In English, we call it Magnesium Chloride. The atomic weight of Magnesium is 24.305, that of Chloride is 35.453, therefore, the molecular weight of MgCl2 is 95.211 (g/mol). The MgCl2 molecule is made up of one Mg2+ ion and two Cl- ions.

  2. MgCl2 has a PH level of approximately 7 when dissolved in water, indicating its neutral properties. It dissolves well in both water and ethanol. During the dissolution process, it undergoes ionization, breaking down into Mg2+ and Cl- ions. Furthermore, MgCl2 has the ability to react with water to form Magnesium Hydroxide and Hydrochloric Acid.

  3. MgCl2 can participate in various different reactions. An example is the reaction between MgCl2 and Ca(OH)2 water, resulting in Mg(OH)2 and CaCl2. This indicates that MgCl2 can react with different metals. MgCl2 can also react with strong acids like H2SO4, producing H2O, MgSO4, and HCl.

  4. MgCl2 can be prepared in several ways. In the laboratory, we can prepare MgCl2 by reacting Magnesium with Hydrochloric acid. On an industrial scale, MgCl2 is typically produced from magnesium ores or sea water, through an evaporation process to remove water and other unwanted substances.
