![Baking Soda vs. Baking Powder: What's the Difference](https://images.medicinenet.com/images/article/main_image/family-cooking-baking-senior-child-parenting-kitchen.jpg?output-quality=75)
Baking soda and baking powder are both used as leavening agents that make baked goods rise due to the release of carbon dioxide, giving them a light and fluffy texture.
Even if you are an experienced baker, however, it can be easy to confuse baking soda and baking powder, since they look and sound so similar.
Learn about the differences between baking soda and baking powder and whether you can substitute one for the other in recipes.
What is baking soda?
Baking soda is made of sodium bicarbonate.
When an acid is combined with sodium bicarbonate, it reacts and results in the formation of CO2 bubbles that resemble liquid foam. This process is called chemical leavening, allowing baked goods to rise.
Most recipes that call for the use of baking soda will also list an ingredient that contains acid, such as buttermilk, yogurt, or vinegar.
What is baking powder?
Baking powder, on the other hand, contains both sodium bicarbonate and acids.
One of the acids is monocalcium phosphate. As soon as baking powder is added to a wet batter or dough, the monocalcium phosphate reacts with the sodium bicarbonate, producing CO2 bubbles and resulting in chemical leavening.
To prolong the chemical leavening process, baking powder includes a second acid, either sodium acid pyrophosphate or sodium aluminum sulfate. Both acids must be wet (mixed into the batter) and heated before they begin to react with sodium bicarbonate. This makes the batter rise for a longer period, resulting in more bubbles and therefore a fluffier result.
Can baking soda and baking powder be substituted with each other?
Baking soda and baking powder can be interchanged in recipes, but it may affect the texture and flavor of the final product.
Baking soda requires an acidic substance in order to activate, whereas baking powder requires a watery liquid.
Substituting baking powder for baking soda
While baking powder can be used in place of baking soda, you cannot use the same quantity. Because baking powder is not made entirely of sodium bicarbonate, you may need to use 3-4 times as much baking powder to achieve the desired rising.
Because you will have to use much more baking powder in place of baking soda, it can cause your final product to have a slightly bitter or chemical taste.
Substituting baking soda for baking powder
Because baking soda is stronger than baking powder, you only need a small amount—about 3-4 times less—if you are replacing baking powder in a recipe.
Baking soda also requires an acidic component, which the original recipe may not have included. One approach is to add yogurt, lemon juice, or vinegar to activate the baking soda.

Sodium bicarbonate is a chemical compound made of sodium and bicarbonate used to increase the alkalinity of the body. Intravenous sodium bicarbonate is also used as an antidote for metabolic acidosis due to toxicity from many drugs. Oral sodium bicarbonate is an antacid used to temporarily relieve symptoms of acid indigestion, heartburn, and upset stomach. Common side effects of sodium bicarbonate include excessive alkalinity (metabolic alkalosis), high sodium levels in blood (hyponatremia), low potassium levels (hypokalemia), low calcium levels (hypocalcemia), cerebral hemorrhage, increased acid level in the brain tissue (intracranial acidosis), exacerbation of congestive heart failure (CHF), swelling (edema), and others.
