What is Magnesium Sulfate (MgSO4)?

MgSO4 is an not natural salt with a chemical surname Magnesium sulfate. It is likewise known together Sulfuric acid magnesium salt or Magnesium sulfate anhydrous. That is generally referred to together Epsom salt. Magnesium sulfate is a crystalline solid that has a white appearance and is odorless. It is majorly offered as a bath soak to eliminate sore muscles, to ease the pain of sprains and also bruises, etc. It additionally helps in the removed of splinters and is fairly effective.

Properties that Magnesium sulfate – MgSO4

MgSO4Magnesium sulfate
Molecular Weight/ Molar Mass120.366 g/mol
DensityAnhydrous: 2.66 g/cm3
TasteBitter taste, Saline
Melting Point1,124 °C

It is essential to note that anhydrous magnesium sulfate undergoes decomposition in ~ temperatures above 1124 degrees Celsius. Because MgSO4 is an ionic salt, that exhibits high solubility in water. That can also be provided that the solubility of magnesium sulfate in water increases when the temperature is increased. For example, the solubility of anhydrous MgSO4 in water at a temperature of 0 oC is 269 grams per litre. When the temperature is raised to 100 oC, the solubility that this ionic salt in water practically doubles come 502 grams every litre. 

Magnesium sulfate is recognized to be a ingredient of many twin salts (ionic salt containing more than one cation or an ext than one anion). Typically known twin salts comprise MgSO4 encompass potassium magnesium sulfates and also sodium magnesium sulfates. Under standard conditions for temperature and pressure (STP), MgSO4 exists as a white crystalline solid i m sorry does no have any type of characteristic odour.

Structure the MgSO4 Molecules

The structure of a magnesium sulfate molecule is shown below. Keep in mind that MgSO4 molecules contain one Mg2+ cation (the magnesium ion) and also one SO42- anion (the sulfate anion).


An ionic shortcut is formed in between the magnesium cation and the sulfate anion in magnesium sulfate. In the sulfate anion, there exist two sulphur-oxygen dual bonds and also two sulphur-oxygen single bonds. The oxygen atom that are singly bonded to the sulphur atom each host a negative charge of magnitude -1. Therefore, the complete charge top top the sulphate anion is -2. The charge on the magnesium cation has a magnitude of +2. Therefore, the optimistic and an adverse charges in this ionic link cancel each other out, bring about a neutrally charged magnesium sulphate molecule. However, when this link is dissolved in water and other polar solvents, the magnesium and the sulphate ion dissociate.

Uses the Magnesium Sulfate

It is supplied in agriculture to boost the magnesium and also sulphur content in the soil.It is provided in do beer as a imminent salt.It is offered as a coagulant to do tofu.It is offered in organic synthesis as a desiccant.Consumption that magnesium sulfate orally together osmotic purgative or saline laxative.Medically that is provided in IV (intravenously) to regulate seizures in pregnant women.

One the the most vital applications that magnesium sulfate is in the preparation of intravenous magnesium, a vital medication because that the treatment of eclampsia. The is also used in replacement therapies for the therapy of magnesium deficiency. The can also be detailed that magnesium sulfate have the right to be employed as a coagulating agent because that the preparation of particular food items choose tofu. 

Health Hazards linked with Magnesium Sulfate

This link is attention when provided in a higher dose than that is encourage by your physician or instructed top top the package. A high dosage the this compound causes serious side effects and also can likewise be life-threatening. Abnormally high concentrations of magnesium in plasma can an outcome in a medical problem known as hypermagnesemia.

Frequently Asked inquiries – FAQs

1. Is magnesium sulfate a link or mixture?Ans: Magnesium sulfate, MgSO4, is a colourless crystalline substance formed by the sulphur dioxide and air reaction the magnesium hydroxide.

2. Is magnesium sulfate dissolve in alcohol?Ans: Magnesium sulfate heptahydrate is a white, crystalline, or brilliant, generally needle-like crystals. It is conveniently soluble in water, in boil water an ext easily soluble, and also in alcohol essentially insoluble.

3. What is the hydrating formula because that MgSO4?Ans: To attain the mole ratio, division the mole of water by moles of anhydrate. 5 H2O/1 mole MgSO4 mole = 5:1. To create the equation, use the mole ratio. Because for every 1 mole the MgSO4 there are 5 mole of H2O, the formula is 5H2O MgSO4.

4. What is magnesium sulfate heptahydrate provided for?Ans: one of the main applications the magnesium sulfate is come be used as a fertilizer in farming and gardening. For bath salts, magnesium sulfate is used.
