On the other hand, baking soda, also known as sodium bicarbonate, is a common leavening agent used in baking. It reacts with acidic ingredients, such as buttermilk, yogurt, lemon juice, or vinegar, to produce carbon dioxide gas, which helps dough or batter rise during baking. Baking soda is often used in recipes for cakes, cookies, muffins, and quick breads.
