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. Unlike baking powder, which contains acidic ingredients, however, baking soda is a single compound composed of only four elements: sodium, hydrogen, carbon and oxygen. Sodium Sodium is an alkali metal that bonds readily with other elements or ions.

It's often used in cookies because they contain acidic ingredients such as buttermilk, molasses, citrus juice, cocoa or brown sugar. Because of this, using a baking soda substitute will not work on cookies that rely heavily on acidic ingredients for flavor or texture development, such as ginger snaps or lemon cookies.
