In this equation, the hydrogen ions (H⁺) from the acid react with the bicarbonate (HCO₃⁻) ions from sodium bicarbonate, resulting in the production of carbon dioxide (CO₂), water (H₂O), and sodium ions (Na⁺). The effervescence observed during this reaction is due to the rapid release of carbon dioxide gas, which is why baking soda is often used in cooking and baking to create lift and texture in baked goods.
