    Why do baking soda and vinegar react when combined?

    A:

    When combined, baking soda and vinegar release a fizzy foam, caused by the release of carbon dioxide when the two chemicals react. Baking soda, which is chemically known as sodium bicarbonate, is a basic substance, while vinegar, also known as acetic acid, is acidic. Combining the two results in a double displacement reaction in which the biproducts are water, carbon dioxide and aqueous sodium bicarbonate.

  • Q:

    What neutralizes vinegar?

    A:

    Vinegar is a solution of acetic acid, which is a weak acid, and can be neutralized by adding a strong base, such as sodium hydroxide. In such a neutralization reaction, the pH of the resulting solution is greater than 7, unlike in strong acid and strong base reactions where the pH is close to 7. Acetic acid cannot be completely neutralized by a weak base, such as ammonia.
