Why Vinegar and Baking Soda Fizz Together

Vinegar is an acid (acetic acid) and baking soda is a base (sodium bicarbonate).
When mixed, they react in a classic acid–base neutralization.
The fizz comes from carbon dioxide gas rapidly bubbling out.
Water and sodium acetate are also formed in the reaction.
The gas expansion makes it perfect for homemade volcano science projects.
This reaction is safe, quick, and visually dramatic for demonstrations.
Temperature can affect how fast and strong the fizzing happens.
Vinegar strength changes the reaction intensity—the more acidic, the fizzier.
Baking soda’s fine powder form helps it dissolve and react quickly.
It’s a fun way to see chemistry in action using everyday items.
