univerkov | March 10, 2021 | education

Na2CO3 – salt;
HCl is acid;
the reaction between salt and acid can occur only under the conditions that one with the product will be a gaseous substance, a precipitate, or water will be obtained. In this case, carbonic acid (H2CO3) is obtained – a weak dibasic acid which, under normal conditions, decomposes into carbon dioxide and water.
We place the coefficients and get the leveled ones:
Na2CO3 + 2HCl = H2O + CO2 + 2NaCl
