MgCl2 Molar Mass

Let us know how much MgCl2 Molar Mass is. Magnesium chloride is the name of the chemical compound with the formula MgCl 2 and its various hydrates are MgCl 2 (H 2 O) x . Anhydrous MgCl 2 contains 25.5% element magnesium by mass. These salts are typical ionic halides , which are highly soluble in water. Hydrated magnesium chloride can be extract from brine or sea water .

In North America, magnesium chloride is produce primarily from Great Salt Lake brine. Dead Sea in Jordan Valleyextracted in a similar process. Magnesium chloride, in the form of the natural mineral biscophyte , is also extracted (by solution mining) from ancient seabeds, for example, the Zechstein Seabed in northwestern Europe . Some magnesium chloride is formed by solar evaporation of seawater. Anhydrous magnesium chloride is the major precursor of magnesium metal, which is manufactured on a large scale. Hydrated magnesium chloride is the most readily available form.

Composition, preparation, and general properties

MgCl 2 crystallizes in the cadmium chloride motif, which is characteristic of the octahedral Mg center. Several hydrates are known with the formula MgCl 2 (H 2 O) x , and each loses water at higher temperatures: x = 12 (−16.4 °C), 8 (−3.4 °C), 6 (116.7 °C). C), 4 (181 ° C ), 2 (about 300 ° C). In the hexahydrate, Mg is also octahedral , but coordinated to the six water ligands . Thermal dehydration of the hydrates MgCl 2 (H 2 O) x (x = 6, 12) is not straightforward. Anhydrous MgCl 2 is produced industrially by heating the chloride salt of the hexamine complex [Mg (NH 3)6].

As suggested by the existence of some hydrates, anhydrous MgCl 2 is a Lewis acid , although a weak one.

In the Dow process , magnesium chloride is regenerated from magnesium hydroxide using hydrochloric acid <362: Mg(OH) <360.>) + 2HCl( aq ) → MgCl 2 ( aq ) + 2H 2 O ( l )

It can also be prepare from magnesium carbonate by a similar reaction .

Derivatives with tetrahedral Mg are less common. For example ( N (C 2 H 5 ) 4 ) 2 MgCl 4 and adducts such as MgCl 2.


Precursor salts contain metals

MgCl 2 is the main precursor of the metal magnesium. Conversion electrolysis :

MgCl 2 → Ng + Cl 2
is affected by. This process is practiced extensively.

dust and erosion control

Magnesium chloride is one of several substances use for dust control, soil stabilization , and corrosion . Wind erosion mitigation. When magnesium chloride is apply to roads and bare soil areas, there are both positive and negative performance issues that are related to a number of application factors.

trigger support

Ziegler-Natta Catalyst. 16>, to produce polyolefins commercially, incorporate MgCl 2 as a catalytic support . The introduction of MgCl 2 enhances the activity. The development of conventional catalysts and highly stereospecific catalysts allowed ysts for the production of polypropylene .

snow control

Magnesium chloride is use for low-temperature de-icing of highways , sidewalks , and parking lots . When highways are paved due to icy conditions, magnesium chloride helps prevent ice binding, allowing the snow to clear roads more efficiently.

Magnesium chloride is use for pavement snow control in three ways: anti-icing, when maintenance professionals spread it on roads before a snowstorm to prevent ice from sticking and forming ice; Prewetting, which means that a liquid formulation of magnesium chloride is sprayed directly onto the salt as it is spread over a roadside pavement, wetting the salt so that it sticks to the road; and pretreating, when magnesium chloride and salt are mixed together before they are loaded onto trucks and spread on paved roads. Calcium chloride damages concrete twice as much as magnesium chloride. It should be note that the amount of magnesium chloride is consider to be in control when it is use for de-icing as it may cause pollution to the environment.

nutrition and medicine

magnesium chloride. Used in nutritional and pharmaceutical preparations .


Magnesium chloride ( E511 ) is an important coagulant “16” used in the preparation. Soy milk from tofu . In Japan it is sold as nigari ( is 16 , derived from the Japanese word for “bitter”), a white powder produced from seawater followed by sodium cherries . Removed, and the water evaporated. In China, it is called Lushui ( 16 ). Nigari or lushui consists mostly of magnesium chloride, with some magnesium sulfate and other trace elements. It is also an ingredient in baby formula milk.

Horticulture and Gardening

Because magnesium is a mobile nutrient, magnesium chloride can be effectively used as a substitute for magnesium sulfate . (Epsom salt) to help correct magnesium deficiency in plants through foliar feeding . The recommended dose of magnesium chloride is smaller than the recommended dose of magnesium sulfate (20 g/L). This is mainly due to the chlorine present in magnesium chloride, which can easily reach toxic levels if applied in excess or too often.

It has been found that high concentrations of magnesium in tomatoes [16]. And some pepper plants can make them more susceptible to infection with the bacterium Xanthomonas campestris , because magnesium is essential for bacterial growth.


The magnesium value in natural seawater is between 1250 and 1350 mg/L, accounting for about 3.7% of the total seawater mineral content. Dead Sea minerals have a fairly high magnesium chloride ratio, 50.8%. Carbonates and calcium are essential for all growth of corals , 292> coralline algae, clams , and invertebrates . Magnesium can be use by mangrove plants and excessive limewater or natural calcium, alkalinity , and pH beyond 16″ values.


Magnesium ions are bitter-tasting, and magnesium chloride solutions are bitter to varying degrees depending on the concentration of magnesium.

Magnesium toxicity from magnesium salts is rare in healthy individuals with a normal diet, as excess magnesium is readily excrete in the urine by the kidneys . Some cases of oral magnesium toxicity in large amounts of magnesium salts have been describe in individuals with normal renal function, but this is rare. If a large amount of magnesium chloride is eaten, its effect will be similar to that of magnesium sulfate , which can cause diarrhea, although the sulfate contributes to the laxative effect in magnesium sulfate, so the effects from chloride are not as severe.

plant poisoning

Both chloride (Cl) and magnesium (Mg) are essential nutrients for normal plant growth. Too much of one of the nutrients can damage the plant, although folic chloride concentrations are more strongly related to foliar damage than magnesium. High concentrations of MgCl 2 ions in soil can be toxic or alter water relationships such that the plant cannot easily store water and nutrients. Once inside the plant, the chloride moves through the water-conducting system and accumulates at the margins of leaves or needles, where the first die off. Leaves are weakened or killed, which can lead to the death of the tree.

locomotive boiler problem

The presence of dissolved magnesium chloride in wells ( salt water ) used in locomotive boilers on the Trans-Australian Railway caused serious and costly maintenance problems in the steam age. With no points on its route, the line crosses a permanent freshwater waterway, so had to rely on bore water. No cheap treatment of highly mineralized water was available, and locomotive boilers normally ran for less than a quarter of the expected time. In the days of steam locomotives, water was about half of the total train load for the engines. Operator of the line, Commonwealth Railway , diesel-electric locomotive .
