Calcium hydroxide (chemical formula: Ca(OH)2) is a white solid that is slightly soluble in water. Its aqueous solution is strongly alkaline and can turn phenolphthalein red.It has the following main properties:
1. Alkalinity: Calcium hydroxide is a strong base, capable of neutralizing acids to form salts and water.
2. Reaction with carbon dioxide: It reacts with carbon dioxide to form calcium carbonate precipitate, which is commonly used for the detection of carbon dioxide.
3. Reaction with acids: It can undergo neutralization reactions with acids to produce corresponding salts and water.
4. Reaction with salts: It reacts with certain soluble salts (such as copper sulfate) to form precipitates.
5. Poor thermal stability: It decomposes easily upon heating to form calcium oxide and water.Calcium hydroxide is relatively mild in nature but is corrosive, so proper protection should be taken.

1. Construction Industry
• Mortar for Masonry and Plastering: Hydrated lime can be mixed with sand and water to produce lime mortar, which is used for bricklaying, stone masonry, and wall plastering. Lime mortar has excellent plasticity and adhesion, and it provides a certain level of strength after hardening.
• Preparation of Three-in-One Soil: Hydrated lime can be combined with clay and gravel to create a mixture known as "Three-in-One Soil." This material is used for laying floors, constructing simple roads, or as a foundation material.
• Lime Wash for Painting: Hydrated lime can be mixed with water to form lime wash, which is used for painting interior walls and ceilings. Lime wash is breathable and environmentally friendly, making it suitable for damp environments.
2. Soil Improvement
• Neutralizing Acidic Soils: Hydrated lime is alkaline and can neutralize acidic substances in the soil, thereby regulating the soil's pH level. This helps improve the soil's acid-base balance, enhances soil fertility, and promotes plant growth.
• Supplementing Calcium: Hydrated lime provides calcium to the soil, which helps strengthen soil structure and reduce soil compaction. It also has a positive effect on plant growth.
3.Industrial Applications
• Production of Bleaching Powder: Hydrated lime is one of the main raw materials for producing bleaching powder. Bleaching powder as bleaching and disinfecting properties and is widely used in the textile, paper-making, and water treatment industries.
• Wastewater Treatment: Hydrated lime is used to treat acidic wastewater. Through neutralization reactions, it removes acidic substances from wastewater and can also precipitate certain heavy metal ions, reducing the pollution level of the wastewater.
4.Food Industry
• Traditional Food Processing: In the production of certain traditional foods, such as preserved eggs (also known as century eggs or pidan), hydrated lime is an important ingredient. It reacts with the proteins in eggs to create a unique flavor and texture.
• Food Additive: In food processing, hydrated lime is sometimes used as an acidity regulator or stabilizer. However, its use is strictly limited and must comply with food safety standards.
