WHEN A BAKING SODA ADD TO VINEGAR REACTION TAKES PLACE.WHY?
When you mix vinegar and baking soda, a chemical reaction takes place producing a gas.
Vinegar is acetic acid: CH3COOH
Baking soda is sodium bicarbonate: NaHCO3
CH3COOH + NaHCO3 ---> CH3COONa + H2CO3
That last product is carbonic acid which quickly decomposes into
carbon dioxide and water:
H2CO3 ---> H2O + CO2
The CO2 is what you see foaming and bubbling in this reaction.
