Calcium Hydroxide

Calcium hydroxide, also known as slaked lime, is a chemical compound with the chemical formula Ca(OH)2. It is a white, powdery substance that is produced by mixing calcium oxide (quicklime) with water. This process is called slaking, and it produces a strong alkaline solution known as lime water.

Calcium hydroxide has several important uses:

• It is used in the production of cement and mortar.
• It is used in the preparation of ammonia and in the paper industry.
• It is commonly used in agriculture to neutralize acidic soils and improve the soil structure.
• It is used in the process of water treatment to raise the pH of acidic water.

When calcium hydroxide is dissolved in water, it undergoes dissociation to form calcium ions (Ca2+) and hydroxide ions (OH-). This property makes it an important compound in various chemical and industrial processes.
