Being a highly reactive compound, calcium oxide or quick lime reacts with a wide range of other compounds, the study of which is important to understand its chemical properties. Reaction with Water: When Quicklime is put in water, it produces calcium hydroxide, a basic compound used in buildings and the chemical industry. Calcium Oxide Quicklime Calcium oxide (chemical formula: CaO), also called quicklime or burnt lime , is a widely used chemical compound in our daily lives formed by ionic bonding between one calcium atom and one oxygen atom. The white or grayish-white crystalline solid, calcium oxide can be produced in large quantities by driving off carbon dioxide from calcium carbonate. Calcium oxide powder will absorb water to convert itself into lime water or calcium hydroxide and release heat. The ... Quick Lime also known as Burnt Lime , Calcium Oxide, Calcined Lime with a chemical formula of “CaO”. It is formed by burning of Lime Stone (Calcium carbonate) at high degree under controlled environment. Quick Lime is one of the oldest chemical in world and used by many industries. Properties of Calcium Oxide • Quick lime is an amorphous white solid with a high melting point of 2600° • It is a very stable compound and withstands high temperatures. • In the presence of water, it ... Hydrated lime vs. quicklime – understand their unique properties, benefits, and top uses in industrial, agricultural, and environmental applications.
