The common name for sodium bicarbonate is baking soda. This white crystalline powder is a versatile compound used in cooking, especially in baking, where it acts as a leavening agent to help dough rise. When combined with acidic ingredients, such as vinegar or yogurt, baking soda produces carbon dioxide gas, which creates bubbles in the batter, resulting in a lighter texture. Beyond culinary uses, baking soda is also used for cleaning, deodorizing, and in personal care products. It has a wide range of applications due to its alkaline nature and safety for consumption.
