Chemical Properties of CaCO3

The chemical properties of calcium carbonate can be visualized in terms of chemical reaction it undergoes. Let’s have glance on the chemical reactions of CaCO₃

Reaction of CaCO₃ with Hydrochloric Acid (HCl)

Calcium Carbonate on reacting with HCl gives calcium chloride salt and carbon dioxide gas which causes effervesence.

CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + H₂O(l) + CO₂(g)

Thermal Decomposition (Heating) of CaCO₃

Thermal Decomposition of Calcium Carbonate form Calcium Oxide with the release of carbon dioxide

CaCO3(s) → CaO(s) + CO₂(g)

Reaction with Water

Calcium Carbonate is insoluble in water under normal conditions but form calcium bicarbonate when react with carbon dioxide saturated water

CaCO₃(s) + H₂O(l) + CO₂(g) → Ca(HCO₃)₂

Reaction with Acids

Calcium Carbonate when react with acid form calcium salt, water and carbon dioxide is released

CaCO₃(s) + 2H⁺(aq) → Ca²⁺(aq) + H₂O(l) + CO₂(g)

Benefits of Calcium Carbonate

The benefits of Calcium Carbonate are mentioned below:

• Calcium carbonate supports the development and maintenance of robust skeletal structures.
• Adequate calcium intake reduces the risk of osteoporosis, promoting bone density.
• Essential for proper muscle function, calcium carbonate aids in everyday movements.
• Calcium is crucial for transmitting signals between nerve cells, facilitating communication in the nervous system.
• Contributes to the clotting process, preventing excessive bleeding after injuries.
• Calcium supports a healthy heart rhythm and helps regulate blood pressure.
• Regular intake prevents deficiency disorders like hypocalcemia, averting muscle spasms and numbness.
• Vital for fetal bone and teeth development during pregnancy.
• Acts as an antacid, neutralizing stomach acid and alleviating acid reflux.
• Conveniently used as a supplement to meet daily calcium needs when natural sources fall short.

Calcium Carbonate Indication

Calcium carbonate is commonly used as a dietary supplement to address low levels of calcium in the body, supporting bone health and preventing conditions like osteoporosis. It is also employed as an antacid to alleviate symptoms of indigestion or heartburn by neutralizing stomach acid. Always consult a healthcare professional before taking any supplements to ensure they are appropriate for your individual needs and health status.

Calcium Carbonate is a prevalent substance discovered in rocks and shells. Commonly Known as Limestone, Calcium Carbonate exists as a white, powdery compound composed of calcium, carbon, and oxygen.
