The Science Involved
A chemical reaction occurs when you mix baking soda and citric acid with water, producing carbon dioxide and sodium citrate. The fizz that bubbles up in your soda is the carbon dioxide. Soda companies put more carbon dioxide into the liquid soda than can be dissolved to make some sodas extra bubbly and fizzy. Since the carbon dioxide can’t dissolve, it sits in the air space in the soda container on top of the liquid. This carbon dioxide escapes when you open the bottle, making the well-known little “hissing” sound.
