Baking Soda – a white crystalline compound
Preparation of Baking Soda
Baking soda is synthesized through Solvay’s process. Solvay’s process involves the reaction of sodium chloride, ammonia and carbon dioxide in water. The carbon dioxide involved is produced through calcium carbonate and the calcium oxide left is used in recovering ammonia from ammonium chloride. Finally, sodium bicarbonate is produced as one of the end products.
NaCl + H2O + CO2 + NH3 → NH4Cl + NaHCO3
Uses of Baking Soda
It is used in making soft and fluffy bread and cakes due to the production of carbon dioxide when it is heated or mixed in water.
NaHCO3 + H+ → CO2 + H2O + sodium salt of acid
It is used for making soda-acid fire extinguisher.
It is used as an ingredient in the manufacturing of antacids.
