Question

In the given chemical reactions,

$2P + H_{2}O + CO_{2} \rightarrow Q\overset{\quad H_{2}O + CO_{2}\quad}{\rightarrow}2R\overset{\quad NaCl\quad}{\rightarrow}S +$

$NH_{4}Cl$

Identify S.

• A. $Na_{2}CO_{3}$
• B. NaOH
• C. $NaHCO_{3}$
• D. $NH_{3}$

Answer 1

Answer: (C)

$NaHCO_{3}$

Answer 2

: The given equations are involved in solvay process.

$\underset{(P)}{2NH_{3}} + H_{2}O + CO_{2} \rightarrow \underset{(Q)}{(NH_{4})_{2}}CO_{3}\overset{\quad H_{2}O + CO_{2}\quad}{\rightarrow}$

$\underset{(R)}{2NH_{4}HCO_{3}}\overset{\quad NaCl\quad}{\rightarrow}\underset{(S)}{NaHCO_{3}} + NH_{4}Cl$
