1. The method for producing soda ash using the ammonia-alkali process is also known as the (Solvay) process. 2. The mother liquor in the ammonia-alkali process for soda production mainly contains (NH4Cl), as well as unconverted (NaCl) and (NH4HCO3). 3. The reaction equation for the carbonation of ammonium salt to form sodium bicarbonate precipitate is (NaCl + NH3 + CO2 + H2O = NaHCO3 + NH4Cl). 4. The (CO2) used for the carbonation of ammonia solutions and the (lime milk) required for the distillation of ammonium chloride are both derived from the calcination of limestone. 5. The suspension obtained by feeding lime and hot water together into a digester is known as (lime milk), and the reaction equation is (CaO + H2O = Ca(OH)2).
