Sodium bicarbonate also known as baking soda is never used on its own

Sodium bicarbonate also known as baking soda is never used on its own. It is always mixed together with other ingredients, which contain acids. Sodium bicarbonate has a capacity to release carbon dioxide when it is heated. The overuse of baking soda makes baked foods taste unpleasantly bitter and can cause digestion issues. This happens when the incorrect pH level occurs.²

Baking powder is a mixture of sodium bicarbonate and a solid acidic substance. The addition of water makes both elements dissolve and react. Baking powder is preferred over pure baking soda because it is more balanced and its by-products are less alkaline so the taste of the final product is not ruined by too much sodium bicarbonate.²
