SSC MTS 2024 PYQ — Question 46

SSC MTS - 15/10/2024 - (12:30 PM - 2:30 PM) • General Awareness • Q46

What is the product of the following chemical reaction?

NaCl + H2O + CO2 + NH3

Show answer & explanation

Correct answer: A

Explanation

The correct answer is  option 1  i.e.  baking soda .

When sodium chloride (NaCl), water (H2O), carbon dioxide (CO2), and ammonia (NH3) react together, the product formed is sodium bicarbonate, commonly known as baking soda (NaHCO3), along with ammonium chloride (NH4Cl). This chemical process is called the Solvay process, an industrial method used to produce baking soda. In this reaction, ammonia reacts with carbon dioxide and water to form ammonium bicarbonate, which then reacts with sodium chloride to produce sodium bicarbonate and ammonium chloride. Baking soda is widely used in cooking, cleaning, and as a mild antacid, while ammonium chloride is separated and reused in the process.

Other options:

  • Washing soda: Sodium carbonate (Na₂CO₃·10H₂O), obtained by heating baking soda.

  • Gypsum: Calcium sulfate dihydrate (CaSO₄·2H₂O), unrelated to this reaction.

  • Bleaching powder: Calcium oxychloride (CaOCl₂), made from chlorine and slaked lime.
