The equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3) -

NaHCO3 + HC2H3O2 → NaC2H3O2 +  H2O + CO2

The overall process can be summarized by the following word equation:

  • baking soda (sodium bicarbonate) reacts with vinegar (acetic acid) that yields carbon dioxide and water with sodium acetate
  • The chemical equation for the overall reaction is:  

NaHCO3 (s) + CH3COOH (l) → CO2(g) + H2O (l) + NaC2H3O2

  • The chemical reaction actually occurs in two steps.
  1. there is a double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid: NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3
  2. Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:  

H2CO3 → H2O + CO2

Thus, the equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3) -

NaHCO3 + HC2H3O2 → NaC2H3O2 +  H2O + CO2
