The equation NaHCO3 + 2H2SO4 -> Na2SO4 + 2H2O + 2CO2

1. Detailed information about the equation NaHCO₃ + 2H₂SO₄ -> Na₂SO₄ + 2H₂O + 2CO₂:

This chemical equation describes the reaction process between bicarbonate (NaHCO₃) and sulfuric acid (H₂SO₄) to produce sodium sulfate (Na₂SO₄), water (H₂O), and carbon dioxide gas (CO₂).

2. Reaction conditions:

This reaction occurs easily at room temperature and atmospheric pressure. However, the reaction rate can increase when the temperature rises or when using a catalyst.

3. Reaction process:

NaHCO₃ reacts with H₂SO₄, producing Na₂SO₄, H₂O, and CO₂ gas. This is an acid-base reaction where H₂SO₄ is a strong acid and NaHCO₃ is a weak base.

4. Phenomena observed:

During the reaction process, we see the phenomenon of CO₂ gas bubbling from the solution. If the reaction is carried out in a test tube, CO₂ gas can be seen escaping from the top of the tube. This is also a simple experimental way to prove the existence of CO₂ gas.
