Question
Write the chemical equations for the reactions involved in the Solvay process of preparation of sodium carbonate.
Solution
The Solvay process is represented by the below chemical equations:
\[\ce{2NH3 + H2O + CO2 -> \underset{\text{Ammonium carbonate}}{(NH4)2CO3}}\]
\[\ce{(NH4)2CO3 + H2O + CO2 -> \underset{\text{Ammonium bicarbonate}}{2NH4HCO3}}\]
\[\ce{NH4HCO3 + NaCl -> \underset{\text{Ammonium chloride}}{NH4Cl} + NaHCO3}\]
\[\ce{2NaHCO3 -> \underset{\text{Sodium carbonate}}{Na2CO3} + CO2 + H2O}\]
