Find A , B and C in the following reactions: NH 3 + A + CO 2 → NH 4 2 CO 3 NH 4 2 CO 3 + H 2 O + B → NH 4 HCO 3 NH 4 HCO 3 + NaCl → NH 4 Cl + C

Options

  1. AA - H 2 O ;   B - CO 2 ;   C - NaHCO 3
  2. BA - H 2 O ;   B - O 2 ;   C - Na 2 CO 3
  3. CA - H 2 O ;   B - O 2 ;   C - NaHCO 3
  4. DA - O 2 ;   B - CO 2 ;   C - Na 2 CO 3

Correct answer

A. A - H 2 O ;   B - CO 2 ;   C - NaHCO 3

Step-by-step solution

Ammonia reacts with carbon dioxide and water to form ammonium bicarbonate. 2 NH 3 + H 2 O ( A ) + CO 2 ⟶ NH 4 2 CO 3 NH 4 2 CO 3 + H 2 O + CO 2 ( B ) ⟶ 2 NH 4 HCO 3 Ammonium carbonate reacts with sodium chloride to form sodium bicarbonate and ammonium chloride. NH 4 HCO 3 + NaCl ⟶ NaHCO 3 ( C ) + NH 4 Cl
