The formula for calcium hydrogen oxide is Ca(OH)2. This compound is also known as calcium hydroxide, slaked lime, or hydrated lime.
Calcium hydroxide is formed when calcium oxide (CaO), also known as quicklime, reacts with water (H2O) in a process called slaking.
The chemical equation for the reaction is:
CaO + H2O → Ca(OH)2
Key characteristics of Calcium Hydroxide (Ca(OH)2):
- Appearance: It appears as a white powder or colorless crystals.
- Solubility: It has limited solubility in water. A solution of calcium hydroxide in water is known as limewater.
- Basicity: It's a strong base.
- Uses: It is widely used in various applications, including:
- Construction: In mortar and plaster.
- Agriculture: For soil stabilization and pH adjustment.
- Industrial Processes: In the production of paper, sugar refining, and water treatment.
In summary, Ca(OH)2 represents the chemical composition of calcium hydrogen oxide, widely recognized as calcium hydroxide and having diverse applications across industries.
