We conclude that baking soda(base) combines with vinegar(acidic) and bubbles are formed .

∙ 12y agoTo answer this question, you need to understand what is happening in a baking soda volcano!
A baking soda volcano erupts because the baking soda reacts with vinegar to ultimately produce carbon dioxide gas (for more information on this reaction, see the very end of this answer). If trapped in a confined space, the pressure of the gas will increase until it can force it's way out of the container you used to make your volcano. As the gas comes out of solution it makes the liquid frothy and forces it to spill out of your home made volcano container (this is meant to represent the lava erupting from a real volcano).
A real volcano also erupts because of increases of pressure in the magma chamber which ultimately forces it's way to the surface.
So a reasonable conclusion would be to say that your baking soda volcano erupts due to the production of carbon dioxide gas which increases pressure within your home made volcano triggering an eruption. This increase in pressure is also what triggers the eruption of real volcanoes and so your home made volcano erupts due to the same physical cause as a real one!
The chemistry:
In simple terms, the baking soda contains something called sodium bicarbonate, this reacts with a chemical called acetic acid (the stuff that makes vinegar sour) to produce carbonic acid. However carbonic acid is unstable and so splits up into it's separate parts producing carbon dioxide (the gas that makes the froth that causes your eruption) and a solution of dilute sodium acetate.
A slightly more technical description is given below:
This is a neutralisation (acid - base) reaction where the vinegar contains the acid and the sodium bicarbonate forms the base. The reaction occurs as follows:
CH3COOH (acetic acid) + NaHCO3 (sodium bicarbonate) -> NaCH3COO- (sodium acetate) + H2CO3
The H2CO3 is unstable and breaks down to form water and Carbon dioxide (a decomposition reaction): (H2CO3 -> H2O + CO2).

CH3COOH (aq) + NaHCO3 (s) =>H2O (l) + CO2 (g) + CH3COO- + Na+

How do you make a volcano with vinegar?
baking soda and vinegar put the baking soda in first
Which is best to make a model volcano eroupt?
vinegar or baking soda
Why does a fake volcano explode?
Because people put in baking soda, vinegar and red food coloring in the volcano. The baking soda and vinegar makes it explode
What can be added to vinegar to create a reaction?
Everybody knows that baking soda and vinegar make a reaction similar to a volcano
What is the control group to the baking soda volcano?
The control group is the vinegar and the volcano
How do you make a volcano replica with clay and firecrackers?
Red food colouring, Vinegar, and Baking Soda.
What can you do for a volcano project to make the eruption without using baking soda and vinegar or mentos and soda?
Yes I Do Jow Bout You
What makes the reaction in a baking soda and vinegar volcano?
well, the chemicals and molecules in the baking soda and vinegar causes them to react with each other.
What is the formula for a science fair volcano?
vinegar and baking soda
Basic ideas to make a volcano?
The Basic materials to make a volcano are. Mentos,baking soda,vinegar, modeling clay and diet pepsi
What can you use to make an volcanic eruption besides baking soda and vinegar?
Assuming you mean a "chemical volcano", the most commonly used ingredients are baking soda and vinegar, though just about any acid and carbonate will work.
How much baking soda and vinegar does it take to make a volcano explode?
That really depends on how big your volcano is. If you want a nice big explosion fill your volcano up about 1/3 full with baking soda but measure out how much baking soda you used, then add some food coloring to the vinegar and pour the same amount of vinegar as baking soda into the volcano. REMEMBER: Pour the vinegar in quickly otherwise it will start spilling out all over before you even get all of the vinegar in. Now stand baack and watch your volcano go!
