Which chlorides does Li and Mg form?

Answer:

Both LiCl and MgCl₂ are deliquescent, absorbing moisture from the environment and soluble in alcohol and pyridine. As hydrated crystals, they separate from aqueous solutions.

Lithium chloride (LiCl)

• Lithium chloride is a hygroscopic white solid that dissolves in water, alcohol, and ether.
• Hydrochloric acid reacts with lithium hydroxide to produce it.
• The resulting solution is evaporated to get a mixture of saturated solution and lithium chloride crystals.
• Lithium chloride is a solid which absorbs water to form a hydrate, LiCl.H₂O

Magnesium chloride (MgCl₂)

• Magnesium Chloride is also called Magnesium dichloride or magnesium (II) chloride or Chloromagnesite and has one magnesium (Mg) and two chloride ions (Cl-)
• MgCl₂ can be extracted from seawater or brine and is chemically named as Magnesium Chloride.
• Magnesium dichloride and its salts are ionic halides and appear as thin white to gray granules.
• It is odourless and is highly soluble in water. It is widely used as a medicine for various cellular activities.
