Question

Реакция карбоната натрия с соляной кислотой

Answer 1

HCl+Na2CO3=2NaCl+H2O+CO2

Answer 2

Reaction of Sodium Carbonate with Hydrochloric Acid

When sodium carbonate (Na2CO3) reacts with hydrochloric acid (HCl), several products are formed. The balanced chemical equation for this reaction is:

Na2CO3 + 2HCl → 2NaCl + H2O + CO2 In this reaction, sodium carbonate reacts with hydrochloric acid to produce sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). The reaction is a double displacement reaction, where the sodium ions (Na+) from sodium carbonate are exchanged with the hydrogen ions (H+) from hydrochloric acid, resulting in the formation of sodium chloride. Water and carbon dioxide are also produced as byproducts of the reaction.

The reaction can be summarized as follows: - Sodium carbonate (Na2CO3) reacts with hydrochloric acid (HCl). - The sodium ions (Na+) from sodium carbonate combine with the chloride ions (Cl-) from hydrochloric acid to form sodium chloride (NaCl). - Water (H2O) and carbon dioxide (CO2) are also produced.

It is important to note that the reaction between sodium carbonate and hydrochloric acid is a common laboratory demonstration to generate carbon dioxide gas. The effervescence observed during the reaction is due to the release of carbon dioxide gas.
