What is Calcium Oxide?
Calcium oxide is a white crystalline substance (an inorganic compound) having the chemical formula CaO. Its common name is quicklime. Calcium oxide is composed of one calcium (Ca) atom and one oxygen (O) atom, with a chemical formula of CaO.
Calcium oxide has a high melting point of approximately 2,572 degrees Celsius (4,662 degrees Fahrenheit). It has a high density so it is a heavy substance.
Calcium Oxide Common Name
Common Name of Calcium Oxide is Quicklime.
Calcium Oxide Chemical Formula
Chemical Formula of calcium oxide is CaO.
Calcium Oxide Molecular Weight
Molecular weight of calcium oxide is approximately 56.08 amu.
The Molecular Weight of Calcium Oxide can be obtained as
- Atomic weight of calcium is approximately 40.08 grams per mole (g/mol).
- Atomic weight of oxygen is approximately 16.00 g/mol.
Molecular Weight of CaO = Atomic Weight of Ca + Atomic Weight of O
⇒ Molecular Weight of CaO = 40.08 g/mol + 16.00 g/mol
⇒ Molecular Weight of CaO = 56.08 g/mol
Calcium Oxide Melting Point
Calcium oxide has a very high melting point.
Calcium Oxide Melting Point is approximately 2572℃ (4662℉)
This high melting point is characteristic of many ionic compounds, and it reflects the strong electrostatic forces of attraction between the positively charged calcium ions and the negatively charged oxide ions in the crystal lattice of the solid CaO.
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.
