What is magnesium sulfate commonly known as?

Magnesium sulfate is commonly known as Epsom salts. This name comes from the bitter saline spring in Epsom, England, where the compound was originally discovered. Epsom salts are often used for various health and wellness applications, including muscle relaxation, reducing inflammation, and as a laxative. The chemical structure of magnesium sulfate consists of magnesium, sulfur, and oxygen, making it distinct from the other options listed.

Calcium carbonate, potassium chloride, and sodium bicarbonate each represent different compounds with varied uses and compositions. Calcium carbonate is primarily known as an antacid or dietary calcium supplement. Potassium chloride is often used to treat or prevent potassium deficiency. Sodium bicarbonate is known as baking soda and frequently used as an antacid and a leavening agent in baking. Each of these compounds serves its unique functions, but they do not share the same identity or common usage as magnesium sulfate.
