Baking soda is alkaline, a base, with a pH of around 8.1. Vinegar is acidic, and most commercial distilled white vinegars contain 5 percent acetic acid and has a pH of about 2.4. Neutral is 7.0. There is one instance when I recommend combining baking soda and vinegar, and that is in the drain. Sometimes the bubbling and hissing in the drain when you combine these two is enough to dislodge hair and gummy buildup. (I recommend a cup of baking soda down the drain, followed by a cup of vinegar.)
Just like carbon dioxide bubbles in a carbonated drink, the carbon dioxide (that formed as the carbonic acid decomposed) rises to the top of the mixture. This creates the bubbles and foam you see when you mix baking soda and vinegar. If you mix a large amount of baking soda and vinegar in a small container with a narrow opening, expect an impressive eruption! Many science teachers use this simple chemical reaction to teach students about chemistry.
