(D) $N{H_3},{H_2}O,NaCl$

Answer 1

Hint: In order to answer this question, first we will mention the raw materials that are used in Solvay’s Process and then we will explain the whole Solvay’s process with its reactions. And we will discuss more about Solvay's process.

Complete answer: The raw materials used in Solvay’s Process are $NaCl,N{H_3},CaC{O_3}$ .
The Solvay process, often known as the ammonia-soda process, is the most used industrial method for producing sodium carbonate \[\left( {soda{\text{ }}ash,{\text{ }}N{a_2}C{O_3}} \right)\] . During the 1860s, Belgian chemist Ernest Solvay refined the ammonia-soda process into its contemporary form.
Soda ash (mostly sodium carbonate \[\left( {N{a_2}C{O_3}} \right)\] ) is produced by the Solvay process from brine (a source of sodium chloride \[\left( {NaCl} \right)\] ) and limestone (a source of calcium carbonate \[\left( {CaC{O_3}} \right)\] ).
The overall process is:
\[2NaCl + CaC{O_3} \to N{a_2}C{O_3} + CaC{l_2}\]
It takes a lot of work to put this big, comprehensive reaction into action. Carbon dioxide \[\left( {C{O_2}} \right)\] travels through a concentrated aqueous solution of sodium chloride \[\left( {table{\text{ }}salt,NaCl} \right)\] and ammonia in the first step of the process $(N{H_3})$ .
$NaCl + C{O_2} + N{H_3} + {H_2}O \to NaHC{O_3} + N{H_4}Cl$
Hence, the correct option is (A) $NaCl,N{H_3},CaC{O_3}$ .

Note:
The Solvay process is widely utilised in the production of sodium carbonate in industry (soda ash). Ammonium carbonate is formed when carbon dioxide combines with dissolved ammonia, followed by ammonium hydrogen carbonate.
