Properties of Magnesium Chloride
Here in this section, various physical and chemical properties of Magnesium Chloride are discussed as,
Physical Properties of Magnesium Chloride
- It is a white or colorless crystalline solid in nature.
- It is odorless in nature.
- The molecular weight of magnesium Chloride is 95 g/mol.
- The density of magnesium Chloride is 2.32 g/cm3 (anhydrous).
- The melting and boiling point of MgCl2 are 714 °C and 1412 °C respectively.
- It is highly soluble in water or any other polar solvent and partially soluble in non-polar solvents.
Chemical Properties of Magnesium Chloride
- On heating, the water of crystallization is lost gradually and this causes a loss in molecular weight.
- It is prepared by a reaction of magnesium hydroxide with hydrochloric acid.
Mg(OH)2 + 2HCl → MgCl2 + H2O
- It disintegrates as Mg and Cl2 when it acts as a precursor.
- Magnesium Chloride disintegrates into magnesium and chloride ions when added to water.
MgCl2 + H2O → Mg+2 (aq.) + 2Cl-1(aq.)
- Magnesium Chloride reacts with a base to form magnesium hydroxide and a salt
Mg(Cl)2 + 2NaOH → Mg(OH)2 + 2NaCl
Magnesium Chloride Formula
Magnesium Chloride or Magnesium Dichloride or Chloromagnesite is a chemical compound with the molecular formula MgCl2. Magnesium Chloride is an ionic salt that is highly soluble in water. This inorganic compound generally consists of one magnesium ion (Mg+2) and two chloride ions (Cl–). Magnesium chloride crystals can be either hydrated or anhydrous. The magnesium chloride salt can be obtained from the seawater or brine solution. An essential mineral for humans, magnesium chloride is an inorganic compound that occurs naturally and has a wide range of uses in industry and medicine.
