What’s the Difference Between Baking Soda and Baking Powder? (2024)
What if your significant other gifted you baking powder instead of chocolates? What if they invented baking powder? In 1843, British chemist Alfred Bird did just that for his lucky, yeast-allergic, bread-loving, wife. This same recipe for baking powder is used to this day. But when it comes to baking cookies, muffins or cakes, recipes will call for baking soda, baking powder, or both. Just like their names, these products are very similar, but not exactly the same.
The active ingredient in both baking soda and baking powder is sodium bicarbonate, or NaHCO3. This compound acts as a leavening agent — which means that it reacts to release carbon dioxide gas (CO2) which gives bread, cake, and pancakes that fluffy texture we know and love.
Let’s break down the chemistry. There are two things that can trigger this reaction: heat and acid.
In the presence of heat, sodium bicarbonate undergoes what is called a thermal decomposition reaction, releasing a molecule of CO2 for every two molecules of sodium bicarbonate. This occurs at a minimum temperature of around 80°C or 180°F. Since recipes generally require a minimum temperature of 300°F, we’re well above the threshold for this reaction to occur.
In the presence of an acid — which can be in the form of lemon juice, buttermilk, or cream of tartar — sodium bicarbonate undergoes an acid-base reaction. In this case, a molecule of CO2 is released in a 1:1 ratio with sodium bicarbonate. That means that you need half the amount of active ingredient to get the same amount of fluffiness as the previous reaction. An acid-base reaction is preferred in order to maximize the carbon dioxide produced.
So, what’s the difference between baking soda and baking powder? Baking soda is pure sodium bicarbonate. Recipes that already have some sort of acid, buttermilk for example, will generally use baking soda. Baking powder is sodium bicarbonate combined with a powdered acid; it is pre-packaged to react in the presence of moisture and heat. Recipes that don’t already include an acidic component will generally use baking powder. Sometimes both these ingredients are included because some of the acidic component needs to be left behind for taste, for example citric acid from lemon juice.
Since baking soda and baking powder contain the same active ingredient, you can substitute one for the other in your recipes, with some adjustments. Baking soda needs to be supplemented with the addition of an acid, such as cream of tartar, to produce the carbon dioxide gas. Baking powder contains less sodium bicarbonate per a certain volume compared to baking soda, so you would need to scale up the amount of baking powder used. Both substitutions might alter taste and texture slightlydepending on the recipe but will work in pinch in order to get the rise in your dough.

They are both leavening agents, meaning they help baked goods to rise. They look similar, but they have different chemical compositions and uses. Baking soda is pure sodium bicarbonate, whereas baking powder also contains an acid, such as cream of tartar

Potassium bitartrate, also known as potassium hydrogen tartrate, with formula KC4H5O6, is a chemical compound with a number of uses. It is the potassium acid salt of tartaric acid (a carboxylic acid). In cooking, it is known as cream of tartar.

While both products appear similar, they're certainly not the same. Baking soda is sodium bicarbonate, which requires an acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated.
Baking soda is just an alkaline, it needs an acid to react with to leaven.Baking powder is baking soda with a powdered acid, so it leavens on its own. If you don't see an acid in the recipe like buttermilk, vinegar, or lemon, you're going to need baking powder.
Remember that baking soda is 3-4 times stronger than baking powder, so you'll need a lot more baking powder to get the same leavening action. As a general rule, triple the amount of baking powder for the amount of baking soda called for in a recipe. For example, 1 teaspoon baking soda = 3 teaspoons baking powder.
Baking soda and baking powder are both essential pantry staples for bakers. They have long shelf lives, but can they go bad? The answer is yes. Both baking soda and baking powder will eventually expire.
The most common reason is that these recipes contain an acid, but the combination with baking soda is not enough to fully leaven the recipe, so baking powder is used to add the necessary lift.
Quick breads use the chemical leavening agents of baking powder and/or baking soda. Baking powder and baking soda do not require time for rising, so the batter for quick bread is cooked immediately after mixing.
Baking soda is a base, often known as sodium bicarbonate. This implies that when baking soda is dissolved in water, it forms an alkaline solution. A 0.1 molar solution of baking soda, for example, has a pH of around 8.3.
Use of baking soda while baking or making cake, makes the cake taste bitter due to the formation of Sodium carbonate during heating. Hence, to neutralize the formed sodium carbonate and its bitter taste, we use tartaric acid. As an acid tartaric acid neutralizes the base effect of Sodium bicarbonate.
Baking soda is generally about three times stronger than baking powder, so adjust your recipe accordingly. Baking soda and baking powder can produce cookies with different textures. Baking soda is typically used for chewy cookies, while baking powder is generally used for light and airy cookies.
Baking soda is good indefinitely past its best by date, although it can lose potency over time. You can use a rule of thumb—two years for an unopened package and six months for an opened package. While old baking soda may not produce as much leavening action, it is still safe to eat.
Baker's tip: If you wind up with an unlabeled jar of white powder and don't know if it's baking soda or powder, use this test: Put a teaspoon of the powder into a tablespoon of water. If it fizzes, it's baking powder.If it doesn't, it's baking soda.
Cream of tartar is a dry, powder-like, acidic byproduct of winemaking called for in a myriad of different baking recipes (from cookies to cakes to frosting). Grapes are a natural source of cream of tartar's main ingredient: tartaric acid (hence the “tartar” in its name).
How to prepare baking powder. To make baking powder, combine half a teaspoon of cream of tartar and a quarter teaspoon of bicarbonate of soda. This provides the equivalent of one teaspoon of baking powder. To make self-raising flour add one teaspoon of baking powder (or equivalent homemade) to 110g plain flour.
Baking powder is used to increase the volume and lighten the texture of baked goods. It works by releasing carbon dioxide gas into a batter or dough through an acid–base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture.
Baking soda changes the texture of baked goods by causing a batter or dough to spread, while baking powder produces light, fluffy texture. Some recipes may call for baking soda or baking powder on their own, while others may require both ingredients to create the ideal balance for great texture.
Baking soda is typically used for chewy cookies, while baking powder is generally used for light and airy cookies. Since baking powder is comprised of a number of ingredients (baking soda, cream of tartar, cornstarch, etc.), using it instead of pure baking soda will affect the taste of your cookies.
