The reaction pathway for the conversion of CaCO3 to Na2CO3 involves several steps in which different chemical species are formed:
CaCO3 (calcium carbonate) reacts with CO2 (carbon dioxide) to form H2CO3 (carbonic acid): CaCO3 + CO2 + H2O -> H2CO3
Carbonic acid then dissociates into H2O (water) and CO2: H2CO3 -> H2O + CO2
The resulting CO2 can react with CaCO3 to form more carbonic acid, continuing the cycle.
Finally, Na2CO3 (sodium carbonate) can be formed by reacting carbonic acid with sodium hydroxide (NaOH): 2NaOH + H2CO3 -> Na2CO3 + 2H2O
Overall, the conversion of CaCO3 to Na2CO3 involves the formation and dissociation of carbonic acid, which then reacts with sodium hydroxide to produce sodium carbonate.
