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

The chemical equation above represents the chemical reaction that occurs between sodium bicarbonate (NaHCO₃) and sulfuric acid (H₂SO₄) to produce sodium sulfate (Na₂SO₄), water (H₂O), and carbon dioxide gas (CO₂). This reaction is a type of acid-base reaction (also known as a proton exchange reaction).

Reaction conditions: This reaction takes place under room temperature and pressure conditions. However, the reaction rate can increase at higher temperatures.

Reaction process: When sodium bicarbonate interacts with sulfuric acid, it receives a proton from the acid to create water and CO₂ gas. Sodium sulfate is also produced as a by-product.

Observed phenomena: When sodium bicarbonate (usually in the form of white powder) is mixed with sulfuric acid, it will create a bubble of CO₂ gas. The reaction products are sodium sulfate, a white solid, and water. One can observe the bubbling of CO₂ gas and the solid product blending with the water.
