The fizz produced when an Alka-Seltzer tablet is dissolved in water is due to the reaction between sodium bicarbonate, NaHCO₃, and citric acid, H₃C₆H₅O₇:

3 NaHCO₃ (aq) + H₃C₆H₅O₇ (aq) → 3 CO₂ (g) + 3 H₂O (l) + Na₃C₆H₅O₇ (aq)

In a certain experiment, 2.2 g of sodium bicarbonate and 3.6 g of citric acid are allowed to react.
