Question

Which of the following reactions is not a part of solvay’s process for preparation of sodium carbonate?

• A. $2NH_{3} + H_{2}O + CO_{2} \rightarrow (NH_{4})_{2}CO_{3}$
• B. $(NH_{4})_{2}CO_{3} + H_{2}O + CO_{2} \rightarrow 2NH_{4}HCO_{3}$
• C. $2NH_{4}HCO_{3} \rightarrow (NH_{4})_{2}CO_{3} + H_{2}O + CO_{2}$
• D. $NH_{4}HCO_{3} + NaCl \rightarrow NH_{4}Cl + NaHCO_{3}$

Answer 1

Answer: (C)

$2NH_{4}HCO_{3} \rightarrow (NH_{4})_{2}CO_{3} + H_{2}O + CO_{2}$

Answer 2

: $2NaHCO_{3} \rightarrow Na_{2}CO_{3} + H_{2}O + CO_{2}$
