Question

when CO2 is passed through saturated solution of ammonia brine two compounds x and y are formed y is used as antacid and decomposes to form other solid Z identify x,y,z and write chemical equations

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 )
