Why does baking soda and vinegar erupts?

Answer 1

That reaction produces carbon dioxide, and it bubbles quickly out. If you contain the reactants tightly before mixing them, it will cause an eruption of sorts as the reaction happens.

Here is the equation for that reaction:

NaHCO3 + HC2H3O2 --> NaC2H3O2 + H2O + CO2

Answer 2

The noise is just the reaction of the vinegar and baking soda taking place.

Second opinion:

It's hard to argue with that answer, but it might help to add a couple of things.

Vinegar and baking soda react to make sodium acetate, water, and CO2 gas. The CO2 bubbles are continually forming and popping. Those little guys are pretty tiny, but when lots of them are popping at once, it makes some noise. That noise is the fizzing, or sizzling you hear.

Answer 3

because the chemical reaction between the two make carbon dioxide (co2) and they began to rise and erupt.

Answer 4

The chemical formulae for each substance are... C2H4O2 (vinegar) + NaHCO3 (baking soda). When the two substances are mixed, they produce CO2 (carbon dioxide) as a byproduct.
