When the student performs the vinegar test on baking soda (sodium bicarbonate), they can expect it to bubble and foam. This reaction occurs because baking soda is a base, and vinegar contains acetic acid. When mixed, they undergo a chemical reaction that produces carbon dioxide gas, which creates bubbles and foam. Therefore, the correct answer is:
**it will bubble and foam.**
**it will bubble and foam.**
