Heat of Reaction between
Vinegar and Baking Soda


The chemical change that occurs when  vinegar (5% acetic acid) and baking soda (sodium bicarbonate) are mixed together is an example of a gas forming acid/base reaction.  The weak acid, acetic acid, reacts with the weak base, sodium bicarbonate, to form sodium acetate, carbon dioxide gas and liquid water.    In this experiment, we will be combining solid sodium bicarbonate with vinegar.

With this in mind, choose the chemical equation that best describes the reaction we are about to carry out.
