MgOH2s

Mg(OH)₂, commonly known as magnesium hydroxide, is an inorganic compound composed of magnesium, oxygen, and hydrogen. It appears as a white, odorless powder that is insoluble in water and alcohol but dissolves slightly in acids. This compound is widely recognized for its use in antacids and laxatives due to its ability to neutralize stomach acid and relieve heartburn and indigestion.

Magnesium hydroxide forms when magnesium ions (Mg²⁺) react with hydroxide ions (OH⁻). It is often found naturally as the mineral brucite, which is a soft, white mineral with a soapy feel. Industrially, it is produced through the reaction of magnesium chloride or magnesium oxide with a base, such as sodium hydroxide.

One of its primary applications is in pharmaceuticals, where it serves as a key ingredient in over-the-counter medications for acid reflux and constipation. It is also used in fire extinguishers, where its ability to absorb heat and release water vapor helps suppress flames. Additionally, magnesium hydroxide is employed in water treatment to remove heavy metals and other contaminants through precipitation.

The compound is generally considered safe for human consumption within recommended doses, though excessive intake may lead to side effects such as diarrhea or digestive discomfort. In industrial settings, proper handling is advised due to its potential to cause irritation upon skin or eye contact. Its low toxicity and environmental benignity make it a preferred choice in various applications compared to more hazardous alternatives.
