Question

By using which process, sodium carbonate is generally prepared?

• A. Deacon's process
• B. Castner-Kellner process
• C. Nelson cell process
• D. Solvay process

Hint:

Associate key industrial processes with their main products: - Solvay Process \(\rightarrow\) Na₂CO₃ (Soda Ash) - Castner-Kellner/Nelson Cell \(\rightarrow\) NaOH (Caustic Soda) - Haber-Bosch Process \(\rightarrow\) NH₃ (Ammonia) - Contact Process \(\rightarrow\) H₂SO₄ (Sulfuric Acid) - Deacon's Process \(\rightarrow\) Cl₂ (Chlorine)

Answer 1

The Correct Option is D

Step 1: Identify the Industrial Process: Sodium Carbonate (\( \text{Na}_2\text{CO}_3 \)), also known as washing soda, is industrially prepared by the Solvay Process (Ammonia-Soda process).
Step 2: Why other options are incorrect: (A) Deacon's process: Used for the manufacture of Chlorine (\( \text{Cl}_2 \)). (B) Castner-Kellner process: Used for the manufacture of Sodium Hydroxide (\( \text{NaOH} \)). (C) Nelson cell process: Also used for the manufacture of Sodium Hydroxide (\( \text{NaOH} \)).
