Question

Compound A reacts with $\mathrm{NH}_4 \mathrm{Cl}$ and forms a compound B . Compound B reacts with $\mathrm{H}_2 \mathrm{O}$ and excess of $\mathrm{CO}_2$ to form compound C which on passing through or reaction with saturated NaCl solution forms sodium hydrogen carbonate. Compound A. B and C, are respectively.

Select the correct option:

A

$\mathrm{CaCl}_2, \mathrm{NH}_3, \mathrm{NH}_4 \mathrm{HCO}_3$

B

$\mathrm{CaCl}_2, \mathrm{NH}_4^{+},\left(\mathrm{NH}_4\right)_2 \mathrm{CO}_3$

C

$\mathrm{Ca}(\mathrm{OH})_2, \mathrm{NH}_3, \mathrm{NH}_4 \mathrm{HCO}_3$

D

$\mathrm{Ca}(\mathrm{OH})_2, \mathrm{NH}_4^{+},\left(\mathrm{NH}_4\right)_2 \mathrm{CO}_3$
