Write short note on Slaked lime
Slaked lime, also known as calcium hydroxide or hydrated lime, is an inorganic compound derived from limestone or calcium carbonate (CaCO3). When limestone is heated, it undergoes a process called calcination, resulting in quicklime (calcium oxide). When quicklime is combined with water, it forms slaked lime (Ca(OH)2).
Slaked lime has several applications in various industries such as construction, agriculture, and water treatment. In construction, it is commonly used as a key ingredient in mortar, plaster, and whitewash due to its ability to create strong bonds and improve the durability of the material. In agriculture, slaked lime serves as a soil conditioner, helping adjust the soil's pH level and providing necessary nutrients, such as calcium, to the plants. In water treatment, it plays a significant role in the neutralization of acidic water and aids in removing impurities.
This versatile compound is also known for its antimicrobial properties and has been traditionally used in food preservation and medicine. Overall, slaked lime is a valuable material with a wide range of applications across numerous industries.
