Magnesium Oxide vs. Magnesium Hydroxide: What's the Difference?
Magnesium oxide is a compound of magnesium and oxygen (MgO), while magnesium hydroxide contains magnesium, oxygen, and hydrogen (Mg(OH)₂), commonly used as an antacid.
Magnesium oxide (MgO) is a simple oxide of magnesium, formed by the combination of magnesium with oxygen. Magnesium hydroxide (Mg(OH)₂), on the other hand, is a compound consisting of magnesium, oxygen, and hydrogen.
Magnesium oxide is often used as a refractory material due to its high melting point and as a supplement for magnesium deficiency. Magnesium hydroxide is widely known as an antacid and laxative, providing relief from acidity and constipation.
The production of magnesium oxide typically involves the calcination of magnesium carbonate or magnesium hydroxide. In contrast, magnesium hydroxide is usually obtained by mixing a soluble magnesium salt with sodium hydroxide.
In terms of chemical properties, magnesium oxide is a basic oxide and reacts with acids to form salts. Magnesium hydroxide, being a hydroxide, also exhibits basic properties and neutralizes stomach acid effectively.
Magnesium oxide has applications in agriculture as a soil additive and in environmental technology for water treatment. Magnesium hydroxide is used in pharmaceuticals and also as a flame retardant in various materials.
