- Try using different baking soda and vinegar ratios to see how they affect the reaction.
- Add food coloring to the vinegar to create a colorful eruption.
- Test other household substances, such as lemon juice, orange juice, or cranberry juice, to compare their reaction with baking soda.
- Add dish soap and compare the eruptions.
- Try using containers with different size openings to observe the pressure the gas exerts, causing the eruption.
What Makes Baking Soda Fizz?
Baking soda is made up of tiny particles called molecules. Each molecule has three different elements: sodium, hydrogen, carbon, and oxygen.
Something exciting happens when baking soda comes into contact with an acid, like vinegar! The acid (vinegar) and the base (baking soda) react. The vinegar donates a hydrogen ion to the baking soda during this reaction.
The hydrogen ion combines with the bicarbonate ion in baking soda to form carbonic acid. This is unstable and quickly breaks into water and carbon dioxide gas.
The carbon dioxide gas is why baking soda starts to fizz and bubble. The gas tries to escape from the mixture, creating bubbles that rise to the surface. These bubbles make a fizzing sound and give the impression of a mini volcano eruption!
So, when you mix baking soda with an acid like vinegar, you get a fantastic fizzy reaction due to the production of carbon dioxide gas. It’s truly an exciting and visually appealing demonstration of a chemical reaction!

Endothermic Reaction
The reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) is endothermic because it absorbs heat from the surroundings, causing a slight drop in temperature.
This process of taking in energy is what makes the reaction endothermic. And as it takes energy, it produces carbon dioxide gas, which creates all the exciting fizz and bubbles you see! It’s like a bit of science magic happening right before our eyes!
