The reaction between vinegar and baking soda can be written as a double displacement reaction if carbonic acid (H₂CO₃) is considered a product:

HCH₃O₂(aq) + NaHCO₃(aq) NaC₂H₃O₂(aq) + H₂CO₃(aq)

However, carbonic acid readily decomposes into carbon dioxide and water,

H₂CO₃(aq) CO₂(aq) + H₂O()

and the carbon dioxide can escape from the solution as a gas.

The combined equation is

HC₂H₃O₂(aq) + NaHCO₃(aq) NaC₂H₃O₂(aq) + H₂O() + CO₂(g)
