One of the byproduct formed during the recovery of NH3 from solvay process :-

Question

A)NaHCO₃ 

B)Ca(OH)₂ 

C)CaCl₂

D)NH₄Cl

_{​​​​​​}

Answer 1

The correct answer is C) CaCl₂ 

Explanation::-

 

This process is also termed as ammonia recovery .

The calcium hydroxide is reacted with the ammonium chloride separated out of the carbonating tower by filtration:

Ca(OH)₂(aq) + 2NH₄Cl(aq) → CaCl₂(aq) + 2H₂O(l) + 2NH₃(g) 

The ammonia is recycled back into the process to form ammoniated brine.

Calcium chloride is formed as a by-product of the Solvay Process .
