  In the synthesis of sodium carbonate, the recovery of ammonia is done by treating \[N{{H}_{4}}Cl\] with\[Ca{{(OH)}_{2}}\]. The by product obtained in this process is : (a) \[CaC{{l}_{2}}\]                          (b) \[NaCl\]                        (c) \[NaOH\]                      (d) \[NaHC{{O}_{3}}\]

Answer:

  (a) \[2N{{H}_{4}}Cl+Ca{{(OH)}_{2}}\to CaC{{l}_{2}}+2N{{H}_{3}}+2{{H}_{2}}O\]
