The reaction between baking soda (sodium bicarbonate, NaHCO3) and vinegar (acetic acid, CH3COOH) is a chemical reaction that involves an acid-base reaction. So, the correct answer is:
A. Undergoes acid-base reaction
When you mix baking soda and vinegar, the following chemical reaction occurs:
NaHCO3 + CH3COOH -> CO2 + H2O + CH3COONa
In this reaction, the acid (acetic acid in vinegar) reacts with the base (sodium bicarbonate) to produce carbon dioxide gas (CO2), water (H2O), and a salt (sodium acetate, CH3COONa). The production of carbon dioxide gas leads to the characteristic fizzing and bubbling that you observe when these two substances are mixed.
