Q:What is the important character of Chinese made alkali?

(1) NH3 + H2O + CO2 = NH4HCO3 (2) NH4HCO3 + NaCl = NH4Cl + NaHCO3 ↓ (3) 2NaHCO3 (heating) = Na2CO3 + H2O + CO2 ↑ That is: ① NaCl (saturated) + NH3 + H2O + CO2 = NH4Cl + NaHCO3 ↓ ②2NaHCO3 = Heating = Na2CO3 + H2O + CO2 ↑ Ammonia reacts with water and carbon dioxide to form a molecule of ammonium bicarbonate, which is the first step. The second step is: ammonium bicarbonate reacts with sodium chloride to form a molecule of ammonium chloride and sodium bicarbonate precipitation, sodium carbonate is precipitated because it is less soluble.
