Uses of Calcium Oxide
- It is extensively used for medicinal purposes and insecticides.
- It finds its application in the manufacturing of cement, paper, and high-grade steel.
- Lime is used as a reagent in laboratories for dehydration, precipitation reaction, etc.
- It is the cheapest alkali available which is an important ingredient in the manufacturing of caustic soda.
- Calcium is essential to animal life as the constituent of bones, shells, and teeth. The most common of the calcium compounds are calcium carbonate which the potter uses as a source of calcium oxide for glazes.
Important Safety Tips
- There are few things that users should keep in mind regarding Calcium Oxides.
- The reaction between quicklime and water is usually vigorous.
- Quicklime can cause severe irritation, especially when inhaled or if it comes in contact with wet skin or eyes.
- Some of the effects of inhalation include sneezing, coughing, or laboured breathing.
- Additionally, it can also result in abdominal pain, nausea burns with perforation of the nasal septum, and vomiting.
- When quicklime reacts with water it can release enough heat to even ignite combustible materials.
FAQ’s
1. Who Discovered Calcium oxide?
Ans: It was first discovered in England in 1808 when a combination of lime and mercuric oxide was electrolyzed by Sir Humphry Davy.
2. Can you drink Limewater?
Ans: Lime water mimics hydrochloric acid which is found in the stomach and, therefore, helps prevent constipation and conditions such as diarrhoea.
3. Why is calcium important for bones?
Ans: Calcium makes bones more brittle. Getting enough calcium in your diet not only maintains healthy bones but also may help prevent hypertension.
4. What are the two uses of quicklime?
Ans: It is used as a basic flux. It is used in the refining of sugar and as a disinfectant and germicide.
5. Does calcium oxide dissolve in water?
Ans: Calcium oxide dissolves in water and glycerol

report regarding this chemical then contact us support@echem.com.bd.High Reactivity: Calcium oxide (CaO), also known as quicklime, reacts vigorously with water, releasing heat and forming calcium hydroxide (slaked lime).
Purity: Lab-grade calcium oxide is highly pure, ensuring accurate results in chemical reactions and analysis.
Versatility: It is used in various applications, including pH regulation, flue gas desulfurization, and as a reagent in organic synthesis.
Desiccant Properties: CaO effectively absorbs moisture, making it valuable as a drying agent in laboratory settings.
Thermal Stability: With a high melting point (2572°C), calcium oxide remains stable at high temperatures, useful in thermal processes.
Neutralizing Agent: It is commonly used to neutralize acidic environments in both lab and industrial processes.
Chemical Production: CaO is essential in producing calcium carbide, calcium hypochlorite, and other important chemical compounds.
Cost-Effective: Calcium oxide is relatively inexpensive and readily available, making it an economical choice for various laboratory applications.
