Detailed Solution

Quicklime, commonly known as lime, is a chemical compound that is widely used in various industrial processes. The quicklime formula is represented as CaO, where "Ca" stands for calcium and "O" represents oxygen.

What is Quicklime?

Quicklime, or calcium oxide, is an important substance used in the production of cement, in chemical processes, and in the treatment of water. It is created by heating limestone (calcium carbonate) to a high temperature, a process known as calcination. The heat drives out carbon dioxide (CO₂) from the limestone, leaving behind quicklime.

The Quicklime Formula: CaO

The quicklime formula, CaO, indicates that it is made up of one atom of calcium (Ca) combined with one atom of oxygen (O). This simple formula makes it a highly reactive compound, especially when it comes into contact with water, producing calcium hydroxide (Ca(OH)₂) in the process.

Uses of Quicklime

Quicklime has several uses in various industries. It is commonly used in:
