Question

Write the preparation of the following compound with balanced chemical equation:

Baking Soda

Answer 1

Baking soda (sodium bicarbonate NaHCO₃) is primarily manufactured via the Solvay process by reacting saturated brine (NaCl) with ammonia (NH₃), water (H₂O), and carbon dioxide (CO₂). The reaction produces ammonium chloride (NH₄Cl) and precipitates sodium bicarbonate.

\[\ce{NaCl + H2O + CO2 + NH3 -> NH4Cl + NaHCO3}\]
