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.
Both baking soda and baking powder are leavening agents, which is a substance, used to produce fermentation in dough or batter. They are added to baking goods before cooking in order to cause them to âriseâ. Although baking powder contains baking soda, both of these agents are used at different conditions. Baking soda is pure sodium bicarbonate whereas baking powder contains sodium bicarbonate and other acidifying and drying agents such as cream of tartar and starch.
