Question

Which compounds are required to manufacture baking soda?

• A. Sodium hydroxide and water
• B. Water and sodium carbonate
• C. Water and bleaching powder
• D. Common salt, carbon dioxide and ammonia

Answer 1

Answer:

D. Common salt, carbon dioxide and ammonia

• Baking soda, or sodium bicarbonate (NaHCO3), is manufactured industrially using sodium chloride (common salt), ammonia, and carbon dioxide, with water being a key component in the process.

• steps:

• Reacting with Ammonia and Carbon Dioxide: Concentrated brine (sodium chloride solution) is saturated with ammonia and carbon dioxide.

• Formation of Sodium Bicarbonate: This reaction leads to the precipitation of sodium bicarbonate (NaHCO3).

• Separation and Heating: The sodium bicarbonate is filtered, washed, and then heated to produce sodium carbonate (Na2CO3)
