The Solvay Process is a continuous process using limestone (CaCO 3) to produce carbon dioxide (CO 2) which reacts with ammonia (NH 3) dissolved in brine (concentrated NaCl (aq)) to produce sodium carbonate. The steps in the Solvay Process are: Brine Purification. Sodium Hydrogen Carbonate Formation. Sodium Carbonate Formation.
