Expert Answer
No. We cannot use NaOH instead of NaCl in solvay process.
Solvay process was first practiced successfully in Belgium in the 1860s. In this process, sodium chloride as a strong brine is treated with ammonia and carbon dioxide to give sodium bicarbonate and ammonium chloride. The desired sodium carbonate is easily obtained from the bicarbonate by heating. Then, when the ammonium chloride is treated with lime, it gives calcium chloride and ammonia.
If NaOH is used instead of NaCl; the desired product will be not obtained.
