Slaked lime, also known as calcium hydroxide, is a white powder produced by adding water to quicklime (calcium oxide). This process is called slaking, and it results in a substance that is highly alkaline. Slaked lime is commonly used in construction, particularly in making mortar and plaster, as it helps bind materials together and improves durability. In addition to construction, slaked lime has various applications in agriculture, where it is used to improve soil quality by neutralizing acidity. It is also utilized in water treatment processes to remove impurities and in the food industry for certain preservation methods.
