Baking soda is pure sodium bicarbonate. When baking soda is combined with moisture and an acidic ingredient (e.g., yogurt, chocolate, buttermilk, honey), the resulting chemical reaction produces bubbles of carbon dioxide that expand under oven temperatures, causing baked goods to expand or rise.
Baking Soda vs Baking Powder. While baking soda is strictly an alkaline compound, baking powder is sodium bicarbonate already combined with an acid. The acid compound in baking powder is in the form of a salt, which means it will not react with the base until a liquid is added. Baking soda is good to use in recipes which include other acidic ingredients. If a recipe does not contain enough acids, using baking powder is appropriate as it contains its own acid.
