Calcium Oxide Frequently Asked Questions
What is Calcium Oxide?
Calcium oxide is a white crystalline substance(an inorganic compound) having chemical formula CaO and is also known as quicklime.
What are the sources of calcium carbonate?
It is basically found in natural minerals such as limestone, chalk, or marble.
How Calcium Oxide can be used to form Calcium Hydroxide?
Calcium oxide reacts vigorously with water to produce calcium hydroxide [Ca(OH)2] and significant amount of heat is released.
CaO + H2O → Ca(OH)2 + heat
How can Calcium Oxide improves Air and Water Quality?
Calcium Oxide captures sulfur dioxide which helps to reduce acid rain formation and air pollution, contributing to improved air quality and reduced environmental harm and it also aids in improving water quality by reducing hardness and the presence of heavy metals, making it safer for consumption and industrial use.
Why Calcium Oxide is used in Alkaline Battery Production?
Calcium oxide is used as an important component in alkaline batteries, where it helps to regulate the pH of the battery electrolyte.
Is Calcium Oxide Soluble in Water?
Calcium oxide is only sparingly soluble in water. When calcium oxide is added to water, it undergoes a vigorous exothermic reaction to produce calcium hydroxide [Ca(OH)2].
Is Calcium Oxide Ionic or Covalent?
Calcium oxide is an ionic compound. It is formed by the combination of a metal (calcium) and a non-metal (oxygen).
What is the Reaction of Water with Calcium oxide?
This reaction results in the formation of calcium hydroxide [Ca(OH)2] and the release of a significant amount of heat. The equation for this reaction is CaO + H2O → Ca(OH)2
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.
