Aluminum Hydroxide Formula

Aluminum hydroxide is a chemical compound with the formula Al(OH)3. It consists of one aluminum ion (Al3+) and three hydroxide ions (OH-) held together by ionic bonds.

The compound is commonly used as an antacid to neutralize stomach acid in the treatment of conditions such as heartburn, indigestion, and gastroesophageal reflux disease (GERD). When aluminum hydroxide reacts with stomach acid, it forms aluminum chloride and water, which helps to reduce the acidity of the stomach contents.

Aluminum hydroxide is also used as a coagulant in water treatment plants to remove impurities from drinking water. In this application, it acts as a flocculating agent, attracting and binding particles together into larger clumps that can be easily removed through sedimentation or filtration.

The compound has a white, powdery appearance and is odorless. It is insoluble in water but can dissolve in acids and bases. Aluminum hydroxide has a relatively low toxicity and is considered safe for use in food and medicine when taken in appropriate doses.
