Demonstration

Experiment

A student creates a “volcano” by mixing vinegar and baking soda is a Experiment in the following way.

Explanation:

The baking soda and vinegar volcano is a fun chemistry project that a student  can do to simulate a real volcanic eruption or as an example of an acid-base reaction. The chemical reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) produces carbon dioxide gas, which forms bubbles in dishwashing detergent. The chemicals are non-toxic (though not tasty), making this project a good choice for scientists of all ages. The cool red lava is the result of a chemical reaction between the baking soda and vinegar. In this reaction, carbon dioxide gas is produced, which is also present in real volcanoes. As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until—thanks to the detergent—the gas bubbles out of the mouth of the volcano.
