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

$NaCl + H₂O + CO₂ + NH₃ --------> NH₄Cl (Ammonium Chloride)+ NaHCO₃(Sodium Bicarbonate)$
This Reaction is $\bold{exclusively}$ used to prepare Sodium Bicarbonate ($\underline{Baking Soda}$).
Please note that Concentrated NaCl in Water is called $\bold{Brine}.$

Answer 2

NaCl+NH3+H2O +CO2 = NaHCO3 + NH4Cl
