Calcium Hydrogen Carbonate Chemical Formula
On the Correlation between the Chemical Formula of Calcium Bicarbonate
There are many studies on the properties and formulas of various substances. Today, the chemical formula of calcium bicarbonate is $Ca (HCO_ {3}) _ {2} $. This formula does not come out of thin air, but is based on the properties of elements and the law of composition.
Calcium, among the elements, often shows $+ 2 $valence, which is due to its atomic structure and outer electrons. Hydrogen, on the other hand, usually has a $+ 1 $valence, carbon in carbonate is $+ 4 $valence, and oxygen is always $- 2 $valence. For bicarbonate, $HCO_ {3 }^{-}$， The combination of hydrogen, carbon and oxygen is in agreement with each other according to their valence states to achieve charge equilibrium.
When calcium and bicarbonate are combined, because calcium is $+ 2 $valence, and bicarbonate is $- 1 $valence, in order to make the compound electrically neutral, two bicarbonates are combined with one calcium ion, resulting in the formula of $Ca (HCO_ {3}) _ {2} $.
The formation of calcium bicarbonate is mostly due to calcium carbonate encountering water containing carbon dioxide. The reason for the reaction is that calcium carbonate first interacts with water and carbon dioxide. Calcium, carbon, oxygen, water, and carbon dioxide elements in calcium carbonate combine and recombine with each other, resulting in the formation of bicarbonate, which is combined with calcium ions to form calcium bicarbonate.
The property of calcium bicarbonate is soluble in aqueous solution, but its stability is slightly less. It is easy to decompose under heat or decompression. When decomposing, the binding state of each element in calcium bicarbonate changes, the bicarbonate decomposes into carbon dioxide, water, and carbonate, and then combines with calcium ions to form calcium carbonate. In this process, although the valence state of the elements changes, they all follow the rules of chemical change. From this perspective, the chemical formula of calcium bicarbonate is $Ca (HCO_ {3}) _ {2} $, although it is a short formula, but it contains the wonderful principle of elemental combination and reaction changes behind it, which is an important corner of chemical exploration.
