Question
Write a balanced chemical equation for the following.
\[\ce{CO2}\] is passed into a concentrated solution of NaCl, which is saturated with \[\ce{NH3}\].
Solution
\[\ce{\underset{\text{(Ammonia)}}{2NH3_{(aq)}}+H2O_{(l)} + CO2_{(g)}->\underset{\text{Ammonium carbonate}}{(NH4)2CO3_{(aq)}}}\]
\[\ce{\underset{\text{Ammonium carbonate}}{(NH4)2CO3_{(aq)}}+H2O_{(l)} + CO2_{(g)}->\underset{\text{Ammonium bicarbonate}}{2NH4HCO3_{(s)}}}\]
\[\ce{\underset{\text{Ammonium bicarbonate}}{NH4HCO3_{(aq)}} + \underset{\text{From brine solution}}{NaCl_{(aq)}}->\underset{\text{Sodium bicarbonate(precipitate)}}{NaHCO3_{(s)}} + NH4Cl_{(aq)}}\]
