- Carbonated water is a supersaturated carbonic acid solution.
- (That's why it bubbles.) The salt crystals just act as nucleation
- centres which speed up the decarbonation process:
-
- H CO --> H O + CO
- 2 3 2 2

- Many side equilibria are being left out. Finding them and determining

-
- It's the same thing. Baking soda is NaHCO_3. Vinegar is an acid
- so it provides a proton to make H_2CO_3 which then decomposes by the
- reaction shown above.
