Correct option is C
Correct option : (c),
The preparation of baking soda (sodium bicarbonate, NaHCO3 typically involves the reaction between sodium carbonate (soda ash Na2CO3 and carbon dioxide CO2 in the presence of water. The chemical reaction is as follows:
Na2CO3(aq)+CO2(g)+H2O(l)→2NaHCO3(aq)
Information booster:
- Sodium carbonate (Na₂CO₃) reacts with carbon dioxide (CO₂) and water (H₂O).
- The result is the formation of sodium bicarbonate (NaHCO₃), which is the chemical formula for baking soda.
