Calcium carbonate is an ionic, inorganic salt which is known as calcium carbonate. It represents a white crystalline structure at room temperature which is water-soluble. The salt, therefore, is generally found in the hydrated form. Calcium carbonate has a wide range of uses in our day-to-day life. Calcium chloride can be formed by using hydrochloric acid with calcium hydroxide. Calcium carbonate can be used in making roads, de-icing, and in foods as well.
CaCl2 Preparation:
-
By reacting hydrochloric acid with calcium hydroxide, CaCl2 can be obtained.
Ca(OH)2+ 2HCl→ CaCl2+2H2O
-
Calcium carbonate can be obtained from limestone by the Solvay process. The reaction is given below:
2NaCl + CaCO3 → Na2CO3 + CaCl2
CaCl2 properties:
Physical properties of CaCl2:
Density: 2.15g/cm3
Molecular weight: 110.98 g/mol
Boiling point: 1,935 °C
Calcium chloride is mainly found in the dissolved state along with water. In water, the ions get dissociated and provide free calcium cations and chloride anions. This can be further described by the fact that when calcium chloride reacts with the phosphate it gives solid precipitation of calcium phosphate.
3CaCl2 + 2PO3−4 → Ca3(PO4)2 + 6Cl−
CaCl2 Structure:
There are two ionic bonds featured between the single calcium ion and two chloride ions because of their valencies. The valency of calcium ions is +2 whereas the valency of chloride ions is -1. Therefore, to maintain the neutrality of the total charge, two molecules of chloride react with one molecule of calcium.
The formula of calcium carbonate
The chemical formula of calcium carbonate is CaCl2. The ionic compound consists of a calcium cation along with two chloride anions reacting with each other to maintain the neutrality of the compound. The formation of calcium carbonate mainly occurs when limestone reacts with hydrochloric acid.
CaCl2 Uses:
-
Calcium carbonate can be used for the preservation of foods, food additives, for de-icing roads in winter, and many more.
-
Calcium carbonate is also used during water treatment to the plants.
-
Calcium carbonate also has its application in the field of metallurgy, oil well drilling, rubber, dye industry, and so on.
-
It can also be used in correcting the mineral deficiencies that are found in the brewing industry.
