Magnesium Oxide vs. Magnesium Hydroxide: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 21, 2023
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.

Key Differences

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.
