Question

What happens when a cold and concentrated solution of sodium chloride reacts with ammonia and carbon dioxide? Write the chemical equation of the reaction which takes place.

Answer 1

Sodium hydrogencarbonate (baking soda) is produced when a cold and concentrated solution of sodium chloride (brine) reacts with ammonia and carbon dioxide.

     NaCl + NH₃ + H₂O + CO₂ → NaHCO₃ + NH₄Cl
