The reaction between baking soda and vinegar (acetic acid) is a classic example of an acid-base reaction. When combined, these substances produce carbon dioxide gas, water, and sodium acetate. The chemical equation is:
The release of carbon dioxide gas creates fizzing and bubbling, making this reaction a popular choice for educational demonstrations and science experiments. It is also used in practical applications, such as homemade volcanoes, cleaning, and baking, where the gas helps dough rise.
