Magnéziumhidroxidot

Magnéziumhidroxidot, commonly known as magnesium hydroxide, is an inorganic compound with the chemical formula Mg(OH)2. It is a white, solid substance that is sparingly soluble in water. Magnesium hydroxide occurs naturally as the mineral brucite.

In its pure form, magnesium hydroxide is a fine white powder. It is produced industrially by reacting magnesium salts with a strong base, such as sodium hydroxide, or by the electrolysis of seawater.

Magnesium hydroxide has several important applications. It is widely used as an antacid to relieve heartburn, indigestion, and upset stomach by neutralizing excess stomach acid. It is also used as a laxative to treat constipation, as it works by drawing water into the intestines, softening the stool and stimulating bowel movements.

Beyond its medicinal uses, magnesium hydroxide serves as a fire retardant. When heated, it decomposes and releases water vapor, which can help cool materials and dilute flammable gases. This property makes it useful in plastics, coatings, and rubber.

Additionally, magnesium hydroxide is employed in environmental applications, such as in wastewater treatment to neutralize acidic wastewater and precipitate heavy metals. It is also used in flue gas desulfurization to remove sulfur dioxide from industrial emissions.
