Question

In the following reaction, what is the name of compound ‘A’? \[ \text{NaCl} + \text{NH}_3 + \text{H}_2\text{O} + \text{CO}_2 \rightarrow \text{A} + \text{NH}_4\text{Cl} \]

• A. Sodium carbonate
• B. Ammonium carbonate
• C. Sodium hydrogen carbonate
• D. Ammonium hydrogen carbonate

Hint:

The Solvay process is an industrial method to prepare NaHCO$_3$ using NaCl, NH$_3$, CO$_2$, and H$_2$O. The product is commonly known as baking soda.

Answer 1

The Correct Option is C

This is a reaction used in the Solvay process for producing sodium hydrogen carbonate (baking soda). The combination of sodium chloride, ammonia, water, and carbon dioxide produces sodium hydrogen carbonate and ammonium chloride: \[ \text{NaCl} + \text{NH}_3 + \text{H}_2\text{O} + \text{CO}_2 \rightarrow \text{NaHCO}_3 + \text{NH}_4\text{Cl} \] Hence, compound 'A' is sodium hydrogen carbonate.
