Chemical Reaction of Bath Bombs

Bath bombs primarily fizz due to a chemical reaction between acids and bases. The key ingredients typically include citric acid and sodium bicarbonate (baking soda). When these two compounds come into contact with water, they undergo a reaction that produces carbon dioxide gas. This gas creates the characteristic fizzing effect that bath enthusiasts enjoy.

Citric Acid: A weak organic acid found in citrus fruits, it acts as the acid component in the reaction.
Sodium Bicarbonate: A mild base that reacts with the citric acid when dissolved in water.
Water: The medium that initiates the reaction by dissolving the solid components.

The reaction can be summarized as follows:

Chemical Equation:
C6H8O7 (citric acid) + NaHCO3 (sodium bicarbonate) → CO2 (gas) + H2O + NaC6H7O7 (sodium citrate)
