How is calcium oxide formed?
Calcium oxide is a white crystalline solid with a melting point of 2572̊C. It is manufactured by heating limestone, coral, sea shells, or chalk, which are mainly CaCO3, to drive off carbon dioxide. This reaction is reversible; calcium oxide will react with carbon dioxide to form calcium carbonate.

Lime Water Formula. Properties of Calcium Oxide. Uses of Calcium Oxide. Important Safety Tips. FAQ’s.
Is calcium oxide a gas or solid?
CALCIUM OXIDE is an odorless, white or gray-white solid in the form of hard lumps. A strong irritant to skin, eyes and mucous membranes. Used in insecticides and fertilizers. Calcium oxide is a member of the class of calcium oxides of calcium and oxygen in a 1:1 ratio.
What is the formula for calcium oxide?
The formula for calcium oxide is CaO. Calcium oxide is an ionic compound composed of the metal calcium and nonmetal oxygen. Calcium is an alkali earth metal (group 2/IIA). The atoms of the alkali earth metals have two valence electrons, which they lose when forming ions. Therefore, calcium cations have a charge of 2+.
