**Chemical Formula:** MgO
**Appearance:** A white odorless powder.
**Uses:**
**Catalyst:** Magnesium Oxide can serve as a catalyst or precursor in chemical synthesis reactions and processes.
**Catalyst and Chemical Synthesis:** Used in catalytic converters, petrochemical refining, and organic synthesis to facilitate chemical transformations, promote reactions, and increase product yields.
**Antacid Medication:** Magnesium oxide is used as an active ingredient in antacid medications to relieve symptoms of acid indigestion, heartburn, and upset stomach. When ingested, it reacts with stomach acid to neutralize excess acid and alleviate gastrointestinal discomfort.
