Why does, when mixed with baking soda, vinegar fizz? When mixed in an empty bottle, why does it fizz so much that it makes the bottle cap bust off and explode?
Vinegar is an "acid", baking soda is a "base". When they're mixed together one of the byproducts is lots of carbon dioxide. That is the gas in the fizz. The carbon dioxide gas is much less dense than the liquids, so it takes up more space, and busts off the top of the bottle.
