Key Features
-
Physical Properties
- Magnesium sulfate, with the formula MgSO₄, consists of one magnesium ion (Mg²⁺) and one sulfate ion (SO₄²⁻).
- The magnesium ion is positively charged, while the sulfate ion carries a negative charge, resulting in an ionic bond.
-
Production Methods
- One involves reacting magnesium oxide or hydroxide with sulfuric acid. This method is precise and yields high purity magnesium sulfate.
- Another route includes magnesium chloride reacting with sodium sulfate to produce magnesium sulfate and sodium chloride. This method leverages readily available raw materials and results in a pure product suitable for various applications.
- The material extracted is then further processed to get the desired purity and particle size.

Industrial Applications
- Versatility in Industrial Use
- Pharmaceutical and Medical Applications: The main external use is the formulation as bath salts, especially for foot baths to soothe sore feet. Internally, magnesium sulfate may be administered by oral, respiratory, or intravenous routes. Internal uses include replacement therapy for magnesium deficiency, treatment of acute and severe arrhythmias, as a bronchodilator in the treatment of asthma, preventing eclampsia and cerebral palsy, a tocolytic agent, and as an anticonvulsant.
- Food and Beverage Industry: Magnesium sulfate is used as:
- Brewing salt in making beer
- Coagulant for making tofu
- Salt substitute
- A food additive to add taste to bottled water
