Baking soda, also called sodium bicarbonate, is a common baking ingredient, cleaner, deodorizer and pH regulator. It is commonly sold as a white powder that looks similar to baking powder.

Baking soda and vinegar react with each other because of an acid-base reaction. Baking soda is a bicarbonate (NaHCO 3) and vinegar is an acetic acid (HCH 3 COO). One of the products this reaction creates is carbon dioxide.You can make your own vinegar and baking soda bottle rocket! Take a piece of paper and put some baking soda on it.nswer 4: They react because baking soda is a base and vinegar is an acid dissolved in water. When you mix an acid and a base in a solvent, which in this case is the water, usually the acid transfers hydrogen to the base to form a new compound.
