One of the by-products formed during the recovery of NH 3 from Solvay process is:

Options

  1. ACa ( OH ) 2
  2. BNaHCO 3
  3. CCaCl 2
  4. DNH 4 Cl

Correct answer

C. CaCl 2

Step-by-step solution

The Solvay process is also called ammonia recovery. The calcium hydroxide is reacted with the ammonium chloride separated out of the carbonating tower by filtration. Ca ( OH ) 2 ( aq ) + 2 NH 4 Cl ( aq ) → CaCl 2 ( aq ) + 2 H 2 O ( l ) + 2 NH 3 ( 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.
