Question

what happens when co2 is passed into ammoniacal brine? give the equation. give one use of the product formed

Answer 1

CO2 + 2 NH3 + 2 NaCl + H2O ---- > Na2CO3 + 2 NH4Cl __( in solution ) 

Na2CO3 and NH4Cl can be separated from solution. 

Actually, this reaction is utilized in Chemical Industry 
( Production of Sodium carbonate and Ammonium chloride )

Answer 2

Answer:

This is called the Solvay process (ammonia-soda process), in which sodium bicarbonate (NaHCO₃) is formed. It is a very important process, used by industries for the production of sodium bicarbonate.

This process has four basic steps; passing of carbon dioxide from ammoniacal brine solution, NaHCO₃ (sodium bicarbonate) production, Na₂CO₃ (sodium carbonate) formation, and recovery of NH₄ (ammonia).

The reaction of Solvay process is NaCl + NH₄ + CO₂ → NH₄Cl + NaHCO₃

The uses of sodium bicarbonate (NaHCO₃), the product of this reaction are cleaning formulations, to make bread spongy, reduce acidity in the stomach, a constituent of fire extinguishers, glass making, etc.
