What is fizz reaction?

The fizz reaction refers to the effervescent phenomenon that occurs when an acid reacts with a carbonate or bicarbonate compound, producing carbon dioxide gas, water, and a salt. This reaction is commonly observed when baking soda (sodium bicarbonate) is mixed with vinegar (acetic acid), resulting in the characteristic bubbling or fizzing. The release of gas creates a visual and auditory effect, often used in cooking and educational demonstrations to illustrate chemical reactions.
