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.
This white powder is an alkali (formally known as bicarbonate of soda) that, when combined with acid, produces carbon dioxide and tiny, fizzy bubbles. Bicarbonate of soda is used in commercial cake mixes and flours to improve the effectiveness of another ingredient with which it is often combined â baking powder.When mixed with tartaric acid or lemon juice, it acts as a raising agent in baking. .icarbonate of soda is used in commercial cake mixes and flours to improve the effectiveness of another ingredient with which it is often combined â baking powder.
