Identify the raw materials used in the industrial preparation of Baking Soda (Sodium Bicarbonate).

Correct Answer: NaCl, H₂O, CO₂, and NH₃

Subject: chemistry

NaCl, H₂O, CO₂, and NH₃
Na₂CO₃, H₂O, and CO₂
NaOH and HCl
CaO, Cl₂, and H₂O

Explanation: • Key Fact Baking soda is synthesized using the Solvay process or a similar ammonia-soda process. • Supporting Detail The raw materials required are Sodium Chloride (brine), Water, Carbon Dioxide, and Ammonia. • Related Concept The reaction is: NaCl + H₂O + CO₂ + NH₃ → NH₄Cl + NaHCO₃. • Why wrong options are wrong Na₂CO₃ is washing soda, not a raw material for producing baking soda in this primary industrial method. • Exam Trick Four ingredients: Salt, Water, Gas (CO₂), Ammonia. • Additional Info Heating baking soda (NaHCO₃) produces Sodium Carbonate (Na₂CO₃), CO₂, and water.
