In the synthesis of sodium carbonate, the recovery of ammonia is done by treating `NH_(4)Cl` with `Ca(OH)_(2)`. The by-product obtained in this process is

A

`CaCI_(2)`

B

`NaCI`

C

`NaOH`

D

`NaHCO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Sodium carbonate is synthesised by Solvary ammonia soda process. The reactions involved are
`NH_(3)+H_(2)O +CO_(2) rarr underset("Ammonium bicarbonate")(NH_(4)HCO_(3))`
`NaCI +NH_(4)HCO_(3) rarr underset("Sodium bicarbonate")(NaHCO_(3)) darr +NH_(4)CI`
`2NaHCO_(3) overset(Delta)rarr underset("Sodium carbonate")(Na_(2)CO_(3))+H_(2)O +CO_(2)`
`NH_(4)` is recovered from `NH_(4)HCO_(3)` and `NH_(4)CI` formed during the reaction.
`NH_(4)HCO_(3)overset("Heat")rarr NH_(3)+H_(2)O+CO_(2)`
`underset("Ammonium chloride")(2NH_(2)CI) +Ca(OH)_(2) rarr underset("Ammonia")(2NH_(3))+ underset("Calcium chloride")(CaCI_(2)) +2H_(2)O`
