Preparation of Calcium Oxide

Calcium oxide is prepared by the process called calcination. Calcination involves heating calcium carbonate (CaCO3) to a high temperature, causing it to decompose and release carbon dioxide (CO2), leaving behind calcium oxide (CaO) as the final product.

CaCO3(g) → CaO(s) + CO(g)

Sources of Calcium Carbonate: It can be obtained naturally i.e. occurring in minerals such as limestone, chalk, or marble.

Calcium Oxide

Calcium oxide is a white, caustic alkaline which is solid at room temperature. Calcium Oxide is known as quicklime is a material which is a commonly used material. Calcium Oxide reactivity with water, along with its other chemical properties, makes it a very important chemical in various fields.

In this article we will learn in detail about calcium oxide, its properties, applications and other details in detail.
