1.	In the Solvay process, can we obtain sodium carbonate directly by treating the solution containing (NH4)2CO3 with sodium chloride? Explain.
Answer» No. In Solvay process, ammonium hydrogencarbonate is prepared from ammonium carbonate, which then reacts with sodium chloride to form sodium hydrogencarbonate. Due to low solubility of NaHCO₃, it gets precipitated and decomposes on heating to give Na₂CO₃. We cannot obtain sodium carbonate directly by treating the solution containing (NH₄)₂CO₃with sodium chloride as both the products formed on reaction, i.e., Na₂CO₃ and NH4Cl are soluble and the equilibrium will not shift in forward direction. (NH₄)₂CO₃+ 2NaCl⇌Na₂CO₃ + 2NH₄Cl
