What is Calcium Carbonate?

Calcium carbonate is an inorganic chemic compound with the chemical formula CaCO₃.

Calcium carbonate is one of the well-nigh popular chemicals which is beginning encountered in school classrooms, where the use of chalk (a course of CaCO_iii ) is found. It is found in the earth's chaff.  It is too found in many forms such equally marble, limestone, etc. Although they are available in diverse forms they are chemically similar and just differ physically. They are also referred to as calcite .

Calcium carbonate is a non-toxic and odourless chemical compound ordinarily found every bit a white mineral which occurs naturally in chalks, limestones and marbles.

Commercial Product of Calcium Carbonate

Calcium carbonate is produced commercially in two dissimilar grades. Both grades compete industrially based primarily on particle size and the characteristics imparted to a production.

1. Ground Calcium Carbonate – Produced via extraction and processing of naturally occurring deposits. GCC crystal shape is irregularly rhombohedral and has a broader size distribution.
2. Precipitated Calcium Carbonate – Produced via chemical precipitation via a carbocation process or as a by-product of some bulk chemical processes. PCC crystal shape depends on the production and the product and the particles are more than compatible and regular with a narrow size distribution.

PCC has smaller particles has a higher purity is less abrasive and tends to take college brightness than GCC.

Calcium Carbonate Structure

Construction of Calcium Carbonate

Calcium Carbonate Formula

• It is a chemic compound with the chemical formula CaCO_iii .
• It is a white insoluble powder-like substance which occurs naturally in minerals, chalk, marble, limestone, calcite, shells, pearl, etc.
• Medicinally, information technology is used as an antacid or equally a calcium supplement. It is also used equally fillers in cosmetics. It is added to swimming pools equally a disinfectant amanuensis and as pH corrector.
• It finds extensive usage in the manufacturing industry every bit a building material (marble), ingredient for quick lime and cement.

Training of Calcium Carbonate – CaCO_iii

1. CaCO₃ is obtained by using carbon dioxide and slaked lime as raw materials. When carbon dioxide is passed through slaked lime, calcite is obtained.

Another method to obtain calcite is by calculation sodium carbonate to calcium chloride.

\(\begin{assortment}{l}~~~~~~~~~~~~~~~~~\cease{array} \)

Ca (OH)₂ + CO₂ → CaCO_three + H₂O

\(\begin{array}{l}~~~~~~~~~~~~~~~~~\end{array} \)

CaCl₂ + Na₂CO₃ → CaCO₃ + 2NaCl

When carbon dioxide is passed in excess it leads to the formation of calcium hydrogen-carbonate.

two. On a large scale, information technology is prepared by passing carbon dioxide gas through calcium hydroxide (slaked lime). However, if carbon dioxide is passed in excess, it forms the soluble calcium hydrogen-carbonate.

Ca(OH)₂ + CO₂ → CaCO₃ + H₂O

Properties of Calcium Carbonate – CaCO₃

• It is a fluffy powder.
• It decomposes to give carbon dioxide when heated up to 1200K.
• When information technology reacts with dilute acid, it liberates carbon dioxide equally a past-production.

\(\begin{array}{l}~~~~~~~~~~~~~~~~~\end{array} \)

CaCO₃+H_iiAnd then₄ → CaSO₄+H₂O+CO_two

• At 1200K, calcium carbonate decomposes to requite carbon dioxide and calcium oxide.
  CaCO_iii → CaO + CO₂

• On reacting with dilute acids, calcium carbonate gives carbon dioxide.
  CaCO_three + 2HCl → CaCl₂ + H₂O +CO_two

Application of Calcium Carbonate

• Calcium carbonate is largely employed in the pulp and newspaper industry. It can be used as a filter and pigment, making possible the production of a whiter, college quality paint than other minerals.
• In the structure industry, calcium carbonate is used every bit a filler in physical, increasing its durability and appearance and to purify metals for utilize in construction applications.
• Another application of calcium carbonate is in fertilizers to provide calcium to plants and pH stabilization of the soil.
• Calcium carbonate can also be an additive to food products for livestock animals and humans and as a supplement in vitamins.
• In water and sewer treatment plants, calcium carbonate is employed in the removal of acidity and impurities.

Calcium Carbonate Uses

The listing of uses of calcium carbonate is given below.

• It plays an important role in structure, be information technology as a edifice material (marble) or as an ingredient in cement.
• It is used in medicinal industries which industry antacids, tablets which are made of base materials etc.
• It is used as calcium supplements.
• It is used in the industry of paints, paper, plastics, etc.

Frequently Asked Questions – FAQs

What is the calcium carbonate used for?

It used equally an antacid is calcium carbonate to alleviate heartburn, acid indigestion, and breadbasket upset.

Name the fruit which is rich in calcium?

Apricot, gooseberry, figs, raisins are the fruits rich in calcium.

Is Limestone a calcium carbonate?

It is a sedimentary carbonate stone that often consists of skeletal parts of marine organisms such as coral, foraminiferous, and molluscs.

How practise you identify carbonate salt?

Strong acids, such as muriatic acid, tin be added to appraise whether a mineral or rock contains calcium carbonate. If the sample contains calcium carbonate, carbon dioxide will be fizzed and produced.

What is the formula for calcium carbonate?

The formula for calcium carbonate is CaCO₃.
