What would happen if you put more vinegar than baking soda?

If you add too much vinegar to a baking soda volcano experiment, the mixture will become too acidic and the reaction will not produce as much foam and bubbles. The chemical reaction between baking soda and vinegar is an acid-base reaction, which means that the acid (vinegar) reacts with the base (baking soda) to produce carbon dioxide gas and water. If there is too much acid, the reaction will be overwhelmed and will not be able to produce as much gas. This means that the volcano will not erupt as spectacularly as it would with the correct ratio of baking soda to vinegar.
