What is Magnesium Sulfate (MgSO4)?

MgSO4 is an not natural salt v a chemical surname Magnesium sulfate. That is also known together Sulfuric acid magnesium salt or Magnesium sulfate anhydrous. It is frequently referred to together Epsom salt. Magnesium sulfate is a crystalline solid that has actually a white appearance and also is odorless. That is majorly provided as a bathtub soak to eliminate sore muscles, to lull the pain of sprains and bruises, etc. It likewise helps in the removed of splinters and is rather 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 keep in mind that anhydrous magnesium sulfate undergoes decomposition at temperatures over 1124 levels Celsius. Since MgSO4 is an ionic salt, it exhibits high solubility in water. The can additionally be listed that the solubility that magnesium sulfate in water increases when the temperature is increased. Because that example, the solubility the anhydrous MgSO4 in water in ~ a temperature the 0 oC is 269 grams per litre. Once the temperature is raised to 100 oC, the solubility of this ionic salt in water practically doubles to 502 grams every litre. 

Magnesium sulfate is known to be a component of many dual salts (ionic salt containing much more than one cation or more than one anion). Typically known twin salts include MgSO4 include potassium magnesium sulfates and sodium magnesium sulfates. Under standard problems for temperature and pressure (STP), MgSO4 exists as a white crystalline solid which does not have any type of characteristic odour.

Structure that MgSO4 Molecules

The structure of a magnesium sulfate molecule is portrayed below. Keep in mind that MgSO4 molecule contain one Mg2+ cation (the magnesium ion) and 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, over there exist 2 sulphur-oxygen dual bonds and two sulphur-oxygen solitary bonds. The oxygen atom that space singly bonded to the sulphur atom each hold a an adverse charge of magnitude -1. Therefore, the total charge top top the sulphate anion is -2. The fee on the magnesium cation has actually a magnitude of +2. Therefore, the hopeful and an adverse charges in this ionic link cancel each various other out, resulting in a neutrally charged magnesium sulphate molecule. However, as soon as this link is dissolved in water and other polar solvents, the magnesium and the sulphate ions dissociate.

Uses the Magnesium Sulfate

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

One that the most important applications the magnesium sulfate is in the preparation of intravenous magnesium, a an essential medication because that the therapy of eclampsia. It is likewise used in replacement therapies because that the treatment of magnesium deficiency. The can additionally be listed that magnesium sulfate deserve to be employed as a coagulating agent because that the ready of certain food items prefer tofu. 

Health Hazards connected with Magnesium Sulfate

This link is dangerous when offered in a greater dose 보다 that is encourage by your physician or instructed top top the package. A high dosage the this compound causes serious side effects and can likewise be life-threatening. Abnormally high concentrations of magnesium in plasma can result in a medical problem known as hypermagnesemia.

Frequently Asked questions – FAQs

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

2. Is magnesium sulfate dissolve in alcohol?Ans: Magnesium sulfate heptahydrate is a white, crystalline, or brilliant, typically needle-like crystals. The is readily soluble in water, in boil water much more easily soluble, and also in alcohol essentially insoluble.

3. What is the hydrating formula because that MgSO4?Ans: To acquire the mole ratio, division the mole of water by mole of anhydrate. 5 H2O/1 mole MgSO4 moles = 5:1. To write the equation, usage the mole ratio. Since for every 1 mole that MgSO4 there room 5 mole of H2O, the formula is 5H2O MgSO4.

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