Verified by Experts

The correct answer is:

A = Ca(OH) 2 , B = NH 4 HCO 3 , C = Na 2 CO 3 , D = NH 4 Cl, E = CaCl 2

In the manufacture of sodium carbonate by ammonia - soda process following reactions are involved.

: Ca(OH) 2 CaO + H 2 O ⎯→ Ca(OH) 2

: NH 4 HCO 3 NH 3 + H 2 O + CO 2 ⎯→ NH 4 HCO 3

: Na 2 CO 3 2NaHCO 3 ⎯→ Na 2 CO 3 + H 2 O + CO 2

: NH 4 Cl NH 4 HCO 3 + NaCl ⎯→ NaHCO 3 + NH 4 Cl

(E) : CaCl 2 2NH 4 Cl + Ca(OH) 2 ⎯→ 2NH 3 + 2H 2 O + CaCl 2

(E)

So, A = Ca(OH) 2 , B = NH 4 HCO 3 , C = Na 2 CO 3 , D = NH 4 Cl, E = CaCl 2
