This is a simplified version of the Solvay process, which is used to produce sodium carbonate (Na2CO3) from sodium chloride (NaCl).

NaCl is first electrolyzed to produce sodium metal (Na) and chlorine gas (Cl2).The sodium metal reacts with water to form sodium hydroxide (NaOH) and hydrogen gas (H2).Sodium hydroxide reacts with carbon dioxide (CO2) to form sodium carbonate (Na2CO3).Sodium carbonate can then be reacted with sulfuric acid (H2SO4) to produce sodium sulfate (Na2SO4) and carbon dioxide gas (CO2).Finally, sodium sulfate can be converted back to sodium chloride in a process called the Mannheim process.

Overall, this process can be represented as:
NaCl -> Na + Cl2
2Na + 2H2O -> 2NaOH + H2
2NaOH + CO2 -> Na2CO3 + H2O
Na2CO3 + H2SO4 -> Na2SO4 + CO2 + H2O
Na2SO4 + NaCl -> 2NaCl + Na2SO3

Please note that this is a simplified explanation and the actual industrial processes may involve more steps and complex reactions.
