- AMgSO₄. 7H₂O
- BCaSO₄. 2H₂O
- CZnSO₄.7H₂O
- DCuSO₄.5H₂O
Solution & Step-by-step Explanation
The question asks to identify the correct chemical formula for Epsom salt, specifically highlighting its use as a laxative. Understanding common chemical compounds and their precise formulas is essential in chemistry.
Epsom Salt Definition
Epsom salt is the common name for a hydrated form of magnesium sulfate. It is named after the town of Epsom in Surrey, England, where it was first discovered in a bitter saline spring. Historically and presently, Epsom salt has been used for various purposes, including in health and beauty.
- One of its most notable applications is as a laxative.
- It is also commonly used in bath soaks for muscle relaxation and pain relief.
Chemical Formula of Epsom Salt
The chemical name for Epsom salt is magnesium sulfate heptahydrate. The term "heptahydrate" indicates that each molecule of magnesium sulfate is associated with seven molecules of water of crystallization.
Therefore, the precise chemical formula for Epsom salt is .
Analyzing Chemical Options
Let's examine the provided options to determine which one correctly represents Epsom salt:
Epsom Salt as a Laxative
The effectiveness of Epsom salt as a laxative stems from its magnesium content. When consumed, magnesium sulfate draws water from the body into the intestines through osmosis. This increase in water softens the stool and adds bulk, stimulating bowel movements. It acts as a saline laxative, promoting evacuation of the bowels.
Conclusion on Epsom Salt
Based on the detailed chemical analysis, the correct chemical formula for Epsom salt, which is widely recognized and used as a laxative, is .

Analyzing Chemical Options
Let's examine the provided options to determine which one correctly represents Epsom salt:
| Option | Chemical Formula | Common Name / Description |
|---|---|---|
| 1 | This is magnesium sulfate heptahydrate, which is indeed Epsom salt. It is widely used as a laxative and for various other health and household applications. | |
| 2 | This is calcium sulfate dihydrate, commonly known as Gypsum. Gypsum is primarily used in building materials like plaster and drywall, not as a laxative. | |
| 3 | This is zinc sulfate heptahydrate, sometimes referred to as "white vitriol". It is used as a dietary supplement for zinc deficiency and in various industrial applications, but it is not Epsom salt or primarily known as a laxative. | |
| 4 | This is copper sulfate pentahydrate, also known as "blue vitriol". It is used as a fungicide, algaecide, and herbicide, but it is not Epsom salt or used as a laxative. |
