Calcium hydroxide is a white powdery solid. The chemical formula Ca(OH)2 is commonly known as hydrated lime, slaked lime, and the aqueous solution is called clarified lime water. Calcium hydroxide has the commonness of base and is a strong base. Calcium hydroxide is a strong binary base, but is only slightly soluble in water. Calcium hydroxide is widely used in industry.
Calcium hydroxide is widely used in the construction industry, especially in the production of mortar and concrete. It can improve the properties of materials and is used as a water repellent in some cases.
In agriculture, it is used to reduce soil acidity and thus improve soil structure. It can react with copper sulfate to produce Bordeaux liquid, which is a commonly used pesticide for the control of fruit trees and vegetables.
It plays an important role in sewage treatment. It can neutralize acidic substances in wastewater and react with metal ions to form water-insoluble precipitates, thereby removing harmful substances.
In the sugar making process, calcium hydroxide is used to neutralize the acid in the syrup, and carbon dioxide is then passed to turn the remaining calcium hydroxide into a precipitate, thus reducing the acid taste of the sugar.
Used as an additive in the pharmaceutical and food industries. For example, it can be used as a synthetic raw material for calcium, for the production of calcium cyclopropanate and calcium lactate.
It is used in the production of bleaching powder, hard water softener, disinfection insecticide, hair removal agent for leather, sugar refining and building materials.
