Information on calcium carbonate in chemistry?????

The main component of natural minerals such as marble, limestone, chalk, etc., is calcium carbonate.

1) Physical properties: white solid, insoluble in water.

2) Chemical Properties:

Reacting with acids produces carbon dioxide, a gas that cloudes lime water, which is the easiest way to identify carbonate ions.

The insoluble calcium carbonate in the limestone layer and the water dissolved in carbon dioxide can be converted into calcium bicarbonate, and the water dissolved in calcium bicarbonate can also precipitate calcium carbonate, which is the reason for the formation of the cave.

Molecular Formula CaCO3 is poorly soluble in water and alcohol. Soluble in acid, while emitting carbon dioxide physicochemical properties White powder. Tasteless and odorless. There are two forms: amorphous and crystalline.

Physical properties The crystal shape can be divided into orthorhombic crystal system and hexagonal crystal system, which is columnar or diamond-shaped. Relative density decomposition. The lower melting point is 1289, showing an exothermic reaction. Also soluble in ammonium chloride solution. Stable in the air with a slight moisture absorption capacity.

One CaCO3 molecule has one Ca molecule, which is +2 valence, two C molecules, +4 valence, and three O molecules, which are +2 valence. Ca2+ ions have 2 positive charges and CO3 ions have 2 negative charges.

White solid insoluble in water CaCO3 commonly known as limestone The main component of stone, pure calcium carbonate is called white marble.

It is easy to decompose into CO2 when heated, and Cao easily reacts with acid.

The chemical property of calcium carbonate is that it is easy to decompose at high temperatures.

Calcium carbonate is an inorganic compound, commonly known as: limestone, limestone, stone powder, marble, etc. Calcium carbonate is neutral, basically insoluble in water, soluble in hydrochloric acid. It is one of the common substances on the earth and is found in aragonite and calcite.

Chalk, limestone, marble, travertine and other rocks are also the main components of animal bones or shells. Calcium carbonate is also an important building material and has a wide range of industrial uses.

A type of limestone whose main component is calcium carbonate. It is formed by the accumulation of the remains of paleontology. White, soft, widely distributed, used as a stucco material, etc.

Mineral name: chalk calcite variety.

It means that it can be burned into lime; From Latin.

Refers to burnt lime. Famous origin: The world's famous production area is New York State, USA.

Essex County and other places in the western provinces of Jiang or Yufan in China.

Chalk is mainly composed of the remains of the unicellular plankton chlorella (melolites). It contains spongy bone needles, planktonic foraminifera shells, ammonites, arrowstones, and sea urchins.

and shellfish fossils and other shells of marine animals.

Hail can be identified from the hardness, cleavage of the diamond, light color, vitreous luster, and the characteristics of superbubbles immediately in cold dilute acid. It can also be used for calcium testing. It and dolomite.

It's similar, and it's symbiotic together. However, dolomite has to be in hot hydrochloric acid to have a significant bubble reaction. It differs from aragonite in that it is lighter than aragonite, which has a specific gravity of 5.

Calcium carbonate is an inorganic compound with the chemical formula CaCo.

Calcium carbonate is a carbon-containing compound, inorganic, and it is one of many calcium supplements. Commonly used calcium supplements in the market include calcium carbonate, calcium lactate, calcium citrate, etc. Calcium carbonate is neutral, basically resistant to lead, insoluble in water, soluble in hydrochloric acid.

It is one of the common substances on earth and is found in rocks such as aragonite, calcite, chalk, limestone, marble, travertine, etc.

Physical properties of calcium carbonateThe white solid is good, tasteless and odorless. There are two forms: amorphous and crystalline. The crystalline type can be divided into orthorhombic crystal system and hexagonal crystal system, which is columnar or diamond-shaped.

The relative density decomposes into calcium oxide and carbon dioxide at about 825. The melting point is 1339, and the lower melting point is 1289. Insoluble in water and alcohol.

It reacts with dilute acid and releases carbon dioxide at the same time, showing an exothermic reaction. It is also soluble in ammonium chloride solution and almost insoluble in water.

1.In case of dilute acetic acid, dilute hydrochloric acid, and dilute nitric acid, bubble boiling, and dissolve. When heated to 900 kilopascals, it decomposes into calcium oxide and carbon dioxide.

2.Heating calcium carbonate to 900 degrees at one atmosphere will decompose into quicklime and carbon dioxide (industrially produced CO).

3.Calcium carbonate reacts with dilute hydrochloric acid, which will be effervescent to produce calcium chloride, water and carbon dioxide (laboratory-made CO).

4.Excess carbon dioxide is introduced into water mixed with CaCO3 to form a calcium bicarbonate solution. Calcium carbonate reacts with a carbonic acid solution (rainwater) to form calcium bicarbonate. CO2 is introduced into the turbid lime water, and the precipitation disappears.

The chemical formula of calcium carbonate is: caco. Calcium carbonate is produced by the combination of calcium ions and carbonate ions, so it is both a calcium salt and a carbonate.
