The homemade volcano erupts
because of a chemical reaction between an acid and a base
. The acetic acid present in the vinegar reacts with the sodium hydrogen carbonate in the baking soda and produces carbon dioxide. The base (sodium hydrogen carbonate) undergoes a decomposing reaction when it is exposed to the acid.
How does baking soda explode a volcano?
Put a pile of baking soda on the baking sheet. Put

How do you erupt a volcano without baking soda and vinegar?
Instead of using vinegar,
use ketchup with baking soda
. This is perfect for a volcano effect because the ketchup is already the right color. You can also add liquid dish soap to create more bubbles and foam in the eruption. Add water to create the desired thickness for the lava.
What can children learn from volcano experiment?
The educator develops the children's concept knowledge, vocabulary, and encourages them to make predictions, and explain their thinking. In this hands-on experience, children learn
about how ingredients are combined to create chemical reactions
, and are introduced to the features of volcanic rocks.
What happens when vinegar and baking soda?
When baking soda is mixed with vinegar, something new is formed. The
mixture quickly foams up with carbon dioxide gas
. … Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate.
How do you make a homemade volcano explode?
First, add
1/3 cup of baking soda to
your magma chamber (bottle). Then add about a teaspoon of dish soap for an extra foaming effect, and top it off with several drops each of red and yellow food coloring. Last, when you are ready for the action, pour in 1⁄2 to 1 cup of vinegar and watch the eruption.
How do you make a homemade volcano model?
- 10 ml of dish soap.
- 100 ml of warm water.
- 400 ml of white vinegar.
- Food coloring.
- Baking soda slurry (fill a cup about 1⁄2 with baking soda, then fill the rest of the way with water)
- Empty 2 liter soda bottle.
What does baking soda represent in a volcano?
The red lava is the result of a chemical reaction between the baking soda and vinegar. In this reaction, the
carbon dioxide gas
is produced, pressure builds up inside the plastic bottle until the gas bubbles out of the volcano. This is a good representation of what happens in real volcanoes.
Can I mix baking soda and vinegar to clean?
Here are some recipes to try. Freshen your sink by mixing
one part of baking soda with two parts of vinegar

Always keep the ratio
one-part baking soda to two parts vinegar
. The mixture will fizz and bubble, like your favorite middle school volcano science project.
What happens when you add water to baking soda?
When baking soda or sodium Bicarbonate (NaHCo3) reacts with water
resulting in release of carbonic acid
. The reaction is exothermic that means it gets the heat out. Baking soda is just sodium bicarbonate.
Why does ketchup and baking soda explode?
The ketchup contains vinegar, which is dilute acetic acid. The acetic acid reacts with the baking soda to produce
carbon dioxide gas
. The gas bubbles expand and rise through the liquid, bubbling out the ketchup.
What can I use in place of baking soda?
