The equation Na2CO3 + SO2 + H2O -> 2NaHSO4 + CO2

Detailed information about the equation Na₂CO₃ + SO₂ + H₂O -> 2NaHSO₄ + CO₂
The above chemical equation shows the reaction process between sodium carbonate (Na₂CO₃), sulfur dioxide (SO₂), and water (H₂O) to produce sodium bisulfate (NaHSO₄) and carbon dioxide (CO₂).

Reaction conditions
This reaction usually occurs under standard temperature and pressure conditions. The presence of water is an important factor for the reaction to take place.

Reaction process
During the reaction process, sodium carbonate will combine with sulfur dioxide and water to form sodium bisulfate and carbon dioxide. The presence of carbon dioxide can be checked by using limewater, if gas bubbles or turbidity are formed, it indicates the presence of carbon dioxide.

Phenomena occurring
During the reaction process, an observable phenomenon is the bubbling of CO₂ gas. In addition, there may be changes in color and temperature as the chemical reaction occurs.
