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.
Yes, Baking Powder has a acidic powder mixed with it to create air bubbles, a rising action. Baking Soda does not have this. You could sub if you had some creme of tarter to initiate the soda/acid reaction. Or (depending on the cake recipe) some sour cream, lemon juice, or buttermilk. Still it would be a guess.
