What is Magnesium Chloride and What Makes it Unique?

Magnesium chloride is a inorganic compound and chemical formula is MgCl2. It is a white colored crystalline solid. And Magnesium chloride is a naturally occurring mineral salt found in many parts of the world. 

Magnesium Chloride Formula

Magnesium chloride has the chemical formula MgCl2, consisting of one magnesium atom and two chloride atoms.

Magnesium Chloride Properties

Melting point = 714°C

Boiling point = 1412°C

Density of Magnesium Chloride = 2.32 g/cm³

Solubility = It is highly soluble in water, with a solubility of 54 g/100 mL at 25°C.

Hygroscopicity = It is hygroscopic, it absorbs moisture from the air.

pH = The pH of magnesium chloride is about 6.0 and this is slightly acidic.

Chemical reactivity = It is a stable compound that does not react with most substances. And it reacts with strong oxidizing agents and some metals.

Magnesium Chloride Uses

1. It is used as de-icing on roads, bridges and airports. It prevents the formation of ice by lowering the freezing point of water.

2. It is used as a dust suppression or control agent on paved roads, construction sites, and mining operations.

3. It is used as a source of magnesium in food and pharmaceutical products.

4. It is used to soften water and remove impurities in water treatment.

5. It is used to improve the quality of the soil, it is used as a fertilizer.

6. Textile production, paper manufacturing and fireproofing. Magnesium chloride is used as a catalyst in chemical reactions in industry.

Magnesium chloride benefits

Magnesium chloride is a good source of magnesium, which plays an essential and important role in maintaining healthy levels in the body.

Magnesium chloride also helps lower blood pressure, reduce the risk of heart disease, and improve heart function.

Magnesium chloride helps produce immune cells and reduce inflammation.

Magnesium Chloride side effects

Magnesium chloride (MgCl2) is generally safe for most people. However, there are some side effects associated with excessive consumption of magnesium chloride. 

Here are some possible side effects of magnesium chloride:

1. Digestive issues.

2. Allergic reactions.

3. Interactions with medications.

4. Dehydration.

5. Muscle weakness.

6. Low blood pressure.

Magnesium Chloride Ice Melt

Magnesium chloride is commonly used as an ice-melting agent on roads, bridges, and sidewalks. It is an effective de-icing agent as it lowers the freezing point of water.

Ethyl magnesium chloride on reaction with benzophenone gives which alcohol

When ethyl magnesium chloride reacts with benzophenone, the resulting product is 1-phenylethanol (alpha-phenylethanol). 

This reaction is a Grignard reaction, where ethyl magnesium chloride acts as a nucleophile and attacks the carbonyl group of the benzophenone, forming a magnesium alkoxide intermediate. The intermediate then reacts with water, producing 1-phenylethanol as the final product.

C6H5COC6H5 + C2H5MgCl → C6H5CH2OMgCl + C2H5Cl

C6H5CH2OMgCl + H2O → C6H5CH2OH + MgCl(OH)
