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

`CaCl_(2)`

B

`NaCl`

C

`NaOH`

D

`NaHCO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Sodium carbonate is generally prepared by solvay process. In this process, `NH_(3)` is recovered when the solution containing `NH_(4)Cl` is treated with `Ca(OH)_(2)`. Calcium chlorid eis obtained as a by-product..
`2NH_(40Cl+Ca(OH)_(2) to 2NH_(3)+ CaCl_(2)+2H_(2)O`
