Question

Write a balanced chemical equation for the reaction between calcium bicarbonate and dilute hydrochloric acid.

Answer 1

Hint: Calcium carbonate, also known as calcium hydrogen carbonate, has a chemical formula $Ca{(HC{O_3})_2}$. The term does not refer to a known solid compound, but it only exists in aqueous solution containing calcium, bicarbonate and carbonate ions together with dissolved carbon dioxide whereas hydrochloric acid has formula $HCl$ and it a colorless inorganic chemical and has a distinctive pungent smell.

Complete step by step answer:
A balanced chemical equation is an equation which has an equal number of atoms for each element involved in the reaction. It occurs when the number of the different atoms of elements in the reactant side is equal to that on the products side.
Moreover, chemical equations are balanced in order to satisfy the law of conservation of mass and to establish the mole relationship needed for stoichiometric calculations.
Now, let’s write the balanced chemical equation for the reaction between calcium bicarbonate and dilute hydrochloric acid.
The balanced chemical equation is as shown:
$Ca(HC{O_3}) + 2HCl \to CaC{l_2} + 2{H_2}O + 2C{O_2}$
As we have seen that calcium bicarbonate reacts with hydrochloric acid to produce three products i.e. calcium chloride, carbon dioxide and water.

Note:
Calcium bicarbonate is used to treat symptoms caused by too much acid present in stomach. It is an antacid that works by lowering the amount of acid in the stomach. Moreover, to prepare a saturated calcium-bicarbonate solution, an excess of calcium-carbonate powder is added to distilled water.
