Calcium Oxide Structure
Thus, it can be understood that calcium oxide is an ionic compound featuring an ionic bond between calcium and oxygen.
Lime Water Formula
The formula for lime water is Ca(OH)2 and the chemical name for lime water is calcium hydroxide. When water is added to lime calcium hydroxide Ca(OH)2 is formed according to the following reaction.
CaO + H2O → Ca(OH)2
This reaction is strongly exothermic and takes place vigorously with the formation of clouds of steam.
What is the Difference Between Quicklime and Lime Water?
The chemical formula of lime or quicklime is CaO. The chemical name of lime is calcium oxide. On the other hand, the chemical formula of limewater is Ca(OH)2 and the chemical name of this substance is calcium hydroxide.
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 forms slaked lime. This process is called the slaking of lime.
CaO+H2O → Ca (OH)2
It is an oxide that is basic in nature and forms salts when it comes in contact with an acid.
This compound crystallizes in a cubic crystal lattice.
The standard molar entropy associated with calcium oxide corresponds to 40 joules per mole kelvin.
This compound is known to emit an intense glow when it is heated to temperatures above 2400 degrees celsius.
