In this reaction, baking soda acts as a base, and takes a proton from vinegar, which is an acid. The reaction releases gas because when the baking soda receives the proton, it transforms into water and carbon dioxide.
A Pinch of a Base. If youâve mixed vinegar and baking soda to clean or to make a bottle rocket, youâve seen the results of an alkaline and vinegar mixture. When baking soda takes a proton from vinegar, it turns it into water and carbon dioxide, making it less vinegary. If you add baking soda to a vinegar dish, you wonât get an explosive reaction, but a cool mellowing of its harshness. Stir a pinch of baking soda into the dish and taste it. Add another pinch of baking soda if needed, but no more; too much baking soda creates an obnoxious alkaline taste.
